Titan requires only two things:
1 -- Everyone must be able to dodge well. All attacks are pre-scripted so its a matter of memorization and being ready to run at the right time in the right direction. And of course no lag.
2 -- The DPS must be able to break heart. The more the merrier.

If there was no need to dodge the attacks then there would be nothing of interest to this fight. If too many people fail to dodge then the battle eventually drains resources (healing MP or DPS from attacking) and a loss will occur. Having oodles of HP of course makes up for not being able to dodge, so if having problems dodging, compensate with +HP.

Oh, use Sprint.... all the time its up.
