I main Hunter, then I spend time on my Warlock, and try to keep up with my Titan, which is clearly my least used character. Anyway. I understand the idea of supers countering supers, but I feel like Titan bubbles should be immune to other supers. It's a trade off. Take on the Titan on the inside, or don't. It's weird to make a wall of light that is supposed to protect from incoming sources of damage, that fails from incoming sources of damage. You should have to fight and beat a Titan on his terms to stop his super, otherwise it just isn't very skillful or fun.
