Hope I have a panic super ready. Otherwise once you get hit by a Firebolt with KF and ToF you're basically screwed.
Sunsinger was the easiest class to play through Crimson Doubles by a landslide. We had 14 wins and 1 loss playing as Sunsinger. Playing as dual Hunter, we had 9 wins and 6 losses. We haven't finished Titan, but I believe we're at 2 wins and 1 loss.
Self Res can give you a huge advantage in Elimination style game modes as well. Especially in CD where you get the armor buff on top of your Radiance damage reduction. You can survive a shit ton of damage with that.
