I have not done Titan, but using Manawall will really help, it allows you to cast w/o being pushed back by knock back. Which means less moving and more casting. I am constantly doing more damage than BRDs and DRG(LMAO). The only time other DPS do more damage than a BLM is if the BLM is in constant danger of being interrupted and or in the need to cancel cast to get out of the way of AoE. Again, Manawall, Manaward, Swiftcast, Surecast, will help greatly if you use these. If you're getting info off parcers, you do realize that they are broken right?
