Self rez is a handy thing to have on tap, and Stormcallers add-clearing abilities are not to be underestimated. Hunters Tether is awesome for orb generation (coupled with Stormcaller, OOSH orbs 4 dayz), Bladedancer invis is always useful and Gunslingers? Hmmm, mine armed with Celestial Nighthawk was hitting the SABER boss for 119k during this nightfall...! Bubble bros are awesome for team buffs and orb generation, strikers are lulzy and Hammerbros are great add-clearers, second only to Stormcallers.
