If anyone has ever played with Kaydin we all know how he loves his titans!!! Delete a titan make a hunter. Delete hunter make a titan again. etc. etc.
I have found benefits to all classes. All depends on what you are playing. Every class plays a role in different scenarios. Except maybe the hunter, hated that class until this raid and I'm still not even sure about it. If they didn't come out with the Don't Touch Me's then I'd probably still hate it!
Titan is the strongest class and jumps the highest. But I can't stand the melee. Supers are useful
Warlock is the in between class for agility and armor. Can't stand the jump but like the melee. Love the Nova Bomb and the Fireborn is handy
Hunter is the fastest but weakest. Jump isn't good and neither is the melee. And the supers are not the easiest to spawn orbs for teammates but great for PVP
