Even if there is a little more lag on Titan, the key is knowing his rotation. When you know he will always use move A after move B you can be ready to move.
I did it with pld, pld(we were running him through it), mnk, mnk, drg. That's wayyyy too much melee, but we didn't die to WoTL once. Just got to know it's going to be time to move, moving>dpsing>healing>anything.
