This is the build I will be going with for wipe day and is specific to the Tahiti server.

This is not a "best" hero guide. There really is no "best" hero. Some do better than others but if you dont enjoy their playstyles they won't feel the "best" to you. Example: Blade is a boss killing monster, but I dont like how he plays.

The gearing here is simply what i found on my way to 60, completing the campaign and then immediately doing the cosmic trial and cosmic Ultron after the campaign.

The only farming done is after first hitting Odins Palace in the campaign. I make sure I have both the currency bonus and Odins bonus going and farm MM. took about 40 minutes to get 300 odin marks for my first legendary. 

As thing is not selectable until after you complete your first raft, I repeat the raft with both xp bonuses going and after talk to Stan Lee. This immediately gets me to 20 and right into farming the Kurse terminal until 40-44 at which point I like to work on the campaign since it's not optional the first time. 

Full run was streamed. Just over 4.5 hours in total to get to this point. Any character that you can do this on this quickly is a good hero to begin your early farming with. 

The only tentative changes with the wipe is that 900g will need to be spent at the start to unlock your character and possibly another 900g for the team up. These details aren't finalized outside of that initial hero price. This may make it harder to buy an expensive costume at the start which in this case was 1k. There might also not be any events running. I only ran armor bounties when they were fast terminals because why not. 

Thing has very low crit rate and brute rate being a dur/str character. Before I picked up the legendary and enchanted the catalyst he had only 14% crit rate and 9% brute rate. Enchanting crit rate on the catalyst brought that up to 28% and the 400 on the savage axe brought it up to 33%. A gungnir gets it up to 38%. This is still low compared to what fighting heroes can achieve at this gearing level assuming they found items with the same amount of stats on them, so i find it better to put crit rate and pick up crit rate/brute rate in the IP first before i start hunting for crit/brut damage. However as you can see it only took me 38 minutes to farm for those 300 Odins, so you may as well buy both the axe and gungnir. 

Rotation:

This is actually two builds. The boss or tough terminal/patrol build is above. For easier content where dying is not going to be an issue you would drop  for , swap your talent on row 2 from Clubbering Time to Heavy Hitter and row 5 from I Got This to C'mere Pal. 

The bossing/hard terminals and patrols rotation is to start with , then , , , (if picking up orbs reset it, , (reset by sig), fill with  until 5s left on cooldown of , then . When  ends repeat from the beginning. 

You can face tank everything in this game other than the things that are coded instant kill if you are not somehow fully invulnerable or have an availble death save on an item - charges from Rhino, Juggernaut, Kingpin. 

Gearing: 

It's literally whatever drops for you during the run, but if you have some choices here is a little guidance:

Slots 1-5:

Slots 1, 3 and 4 you want to priotize cosmic items with dur or strength. you can grab a slot 1 with 500 damage and 3 strength and one with 750 damage with no stats and the 500 damage one is still giving you more damage on your abilities. 

You will have zero resources to reroll things so your unique options are if you chooe to spend some time farming before doing the trial/harder cosmic terminals or an event is running that drops a lot of uniques like midtown madness or odins bounty:

his slot 1, but ONLY if it rolls 4 strength. Otherwise a cosmic slot 1 with 4 str or dur will surpass it no matter what it's other stats are.

slot 2 should be either his , a  or a - which ever has more total dur/str as you find.  is your best bet since it can roll 10 total stats intead of 8 on Ben's own and the symbiotes it procs frequently is just another added damage layer.

slot 3 can be his  or  as i found here which had more total stats and is actually my preferred slot 3 due to the +damage.

slots 4 and 5 really dont have good unique options that aren't hard farms. his own are really, really bad.  in slot 5 isn't bad if you can find one with really good rolls AND a dur/str challenge bonus but still pales to a cosmic due to the 1k damage.

I never found a decent catalyst but if you do decide to farm one priotize +xp, shield on medkit and str/dur. 

Relics:

is preferred but i never found any. So i opted for more movement speed  which is nice for this fatty.

Artifacts:

Literally whatever you find. If you can get both normal and advanced  that's some good stuff. The free is good. Both normal and advanced  are good but as with the crystal i only found the advanced versions this run. Honesty whatever you find with dur/str/all stats/phys damage, melee damage, health or some combination work fine for this.

Medallion:

Since you gotta fight him in the campaign anyway, any flavor of  is what you want. If you levelled like I did you can use a  , bonus if it's cosmic as I found on this run. 

 

Uru doesnt matter you dont have any runes and your enchanter is level 1. Insignia doesnt matter but if you find one with crit and brut rating you're golden (i used a green herbie i found when I ran bugle for a bounty. It has literally no stats). Pet doesnt matter assuming you buy one from the G shop at the start price TBD. I rerolled it 3 times using uniques i found and ended up with 3 energy so...honestly it doesnt matter for this day 1 build. 

Infinity points:

put your first points into Temporal Loophle in the Time Stone. up to 150 points total.  moves faster with movement speed which makes filling the bounties and patrol farming very comfortable. Follow up with Mind over Matter in the mind gem,  Superhuman OR 6 strength in the power gem depending on your gearing progression, and 6 durabilty in the space gem. After that you should be able geared well enough to get value out of Mental Focus in mind and Strikethrough in Power. if your brut chance is still absurdly low (under 30%) i would prob put those points into Suiperhuman first and consider moving on to more endgame focused builds like The Rockslide Roller (Bounty Chest & SSB Farm) [1:45 Skrull] - Thing - Marvel Heroes Omega - Item Base

 

Below is the run as it was streamed, time spent farming for the legendary, cosmic trial and then cosmic ultron. No records were beat here but this is what worked the best for me after trying this same on 15 different fresh accounts and that many different heroes starting. I'm sure there are better, but this site has almost no build guides for anything that isn't already pre-farmed or fully endgame.
