The idea of this fight is to learn it. Of course you can't dodge the AOE's if you plan on standing until they appear. Every one of his moves is systematic. Learn the rotations. Phase 4 for example. the pools always appear after the Table flip or the Table Flip/stomps (as stomps are every second rotation). Watch for the moves in our raid group we stand centre under scholar shields count the stomps then scatter. if you are already on the move you will not get hit by them. I play a healer I know how hard it is. I'm watching health bars not the ground beneath my feet. It took our group a week and a half to down titan. Give it some more time and learn his rotations. There are many groups that have titan on farm status. Which means he is not impossible you just need to put in the effort.
