I've played with (and against) AEGabriel, who is pretty much known as the best Titan on Xbox. He only uses Striker though. I'll agree with you that Sunsinger loses to the bubble, but Voidwalker and Gunslinger will usually win. Bladedancer is pretty random and it can go either way. When I see bubbles, I just run away and don't even give them a chance at killing me. I've also been on the receiving end of Suppression Grenades, and they are very annoying. They can just take you out of Radiance or Arc Blade mid-super, but it's happened to me very rarely. I can acknowledge how good Titans are when played well, but I still think anybody using them would do so much better on a Hunter or Warlock. Hunters have the best supers, and Warlocks have the best grenades/melee. Titans have great movement with the controlled lift and max agility, but that's about it...
