This build is super straight forward, it's ranged.  i use all energy abilities, with one aoe phyiscal.  comeuppance procs power doop, cap insignia, and ads weaken.  if used after a basic it deals nice damage as well.  it's also a big reason i chose to use mkraan for generic damage type. 

i run AI hack for aggro help, and with permanent overclocking he does very decent damage.  i suggest the ultron double blade minion.

other talents are traits are easy enough.  since channeled solar beam is our primary dps, rapid absorption is a must for solar recharge.  i run phase protocol for the extra survival and dps boost... not to mention phasing through everything is it's own reward.

i also solar buildup, but i'm not overly sure it's better than solar infusion.  the cooldown reduction... is not as speedy as i'd like it.

lastly focused radiance for added dps.

my rotation typically surface of the sun, channeled solar beam, solar bolt, intangible manipulation, comeuppance, solar overcharge.  i fill with channeled solar beam, and his basic.  ALWAYS apply surface of the sun for BURNING to get the bonus  of pyro's flame thrower  and sunspots dmg and crit towards burning mobs. (he adds the most as long as they are burning) use ur ult at ur discretion.  it constantly get 500k bruts from channeled solar beam, and 5million bruts from sig.

he's underrated and with a few tweeks from gaz he'll be a monster.
