Hey all! I hope you're enjoying Tahiti!
I've been a cap fan since the game was live, even before his 52 rework! A lot has changed since then, and sadly there are bugs, but I think I have ironed most of them out and found a solid build! 3:15 TTK @ 750 IP. Times can be better with a cleaner rotation!

Rotation/Priority:

Try to have at least one serum before using any serum power!

For timing sake 1-4 serum is fine for  and  . You a want full 10 serum for  and  . This may sound annoying, but it will become easier with repitition.

• Use  off cooldown to proc our row 5 talent.
• Hold left click to build serum with 

•  to apply vulnerability

• Use  once you hit 10 serum

•  to gain 5 serum followed by  once you hit 10 serum. 

• Build up 1-3 serum and use  and remember to watch your aim! This skill can easily miss!

Something just doesn't feel right playing Cap without  or but they can delay  if your shield is out doing it's business and that's delaying one of our hardest hitting abilities on a short cooldown.

Alternative Gear Choices:

Slot 1: -->  --> 
• Skrull hammer and vibro aren't far behind a fragment in terms of damage, but fragment has more of a defensive benefit added in. Vibro are ranked lower since skrull hammer is much easier to roll well.

Slot 2: -->  --> 
• The cosmic option here will outperform the other options. The grind can be annoying, but we want those crits! Aim for CSR>BSR with Crit damage and Brut damage on a might cosmic. 
Slot 3: --> 
• Cap's own slot 3 is an excellent source of stats with crit and brut rating on top.

Slot 4:  -->  --> 
• Cap's own unique has a good amount of raw damage (and spirit sustain), but the procs don't quite function as worded so we'd opt for the crit/brut rating. Two of the slot 4s have attack speed as well, which doesn't help much when we're so far into diminishing returns. The skrull uniform will make a considerable difference over the other options.

Slot 5:  --> 
• Cobra is right on par with an octobot. They are both an improvement over cap's slot 5. Cap's slot 5 is still pretty good, but the other 2 options are better. Using Cobra hood would unlock other skill options to replace Airborne Assault. It's great for clearing, but the animation time is longer and it can be subject to animation cancelling. Shield toss would be a good filler since it returns fairly quickly where bounce can go out to narnia before returning and delay your Torqued Shield Throw. 

Ring:   BSR/CDR-->  --> 

Artifacts:  >  >  >  > 

Medals:  are all decent options.

Legendary: i80 if you want a boost to your defenses, but it comes at a heavy toll to your damage.
 is the i70 option

Infinity points:

TIme Gem - Temporal Loophole 38 points

Mind Gem - Mental Focus 150 points

Power Gem - Strike Through 75 points

Reality Gem - Energy 6 points

Space Gem - Durability 6 points

Additional notes:

• You'll want spirit on hit with your catalyst for enough spirit sustain. If you only have medkit, consider running Cap's Boondocker boots for slot 4.
• Cap want's to stack as much crit/brut rating as possible. There arn't many hits going out, so we need those hits to count! If you choose to spend infinity points make sure it's at .6 increments since the system rounds up! A partial percentage as .6 will net you the same gain as a full 1% so don't waste those precious IP!
• Cap's row 5 talent takes us a mile into diminishing returns with attack speed. Stacking additional attack speed is very low priority for this reason. The idea of stacking up serum faster sounds great, but the diminishing returns past 30% are brutal (pun intended). So we stack brutal rating instead!

• Try to only use Vibranium bash immediately following Airboune Assault. There is an odd timing with AA and it's animation can clip your next ability. If this is to happen, let it be the least damaging ability. 

• The serum power damage bonus on our slot 5 can be consumed by procced damage. Try to limit items that proc random damage! This goes for other gear, artifacts, infinity points, insignias ect.

• The damage bonus on our slot 4 cannot be procced by AA. Meteor kick has a 50% proc chance, and I think charge, leap, and backflip around a 30% chance. I wouldn't go too far out of your way to proc it, but if you notice Meteor Kick didn't proc it (it will be the icon for AA in your buffs), don't be afraid to charge out and back in after your Torqued Shield Throw!

• Despite the tooltip's info, Shield Bash does NOT scale off of Deflect rating. It will give you false info if you have serum saying that it's damage has been incresed by X amount of Deflect rating. This is a known bug going back to Gaz. No need to go out of your way stacking deflect rating in this build. It still helps, but only on defense.

• This build is great for starting out, but the NoSerum will have better performance once you have 500-600+ IP. Use the same gear but swap to talents 1:2 (Heroic Strike) and 4:3 (Stabilized Serum) and use Shield Strike (Heroic Strike if spirit issues) for your filler, instead of Vibranium Bash. The rotation is simply hold left click and keep everything on cooldown! It's a much smoother and enjoyable playstyle, once you have the IP.

• Cap's slot 5 will perform better in NoSerum, but it's a little annoying to properly utilize the serum proc. When your serum powers come off cooldown, let go of Heroic Strike/Shield Strike and use your serum powers one after another. The proc will grant damage rating to your next ability, but that can be consumed by anything, including damage procs. So we want to buff our harder hitting abilities. Once you cycle through your serum powers, resume Heroic Strike/Shield Strike.
