This is an AST question, but since it concerns DPSers, I thought it would be better to ask on the DPS forums instead.
Are there any card buffs that would be great on a specific DPS class and are there any card buffs that would be bad to use on a DPS class?
I asked around and the answers I got were not to use "The Spear" on Ninjas and not to use "The Ewer" on BLMs since it might ruin their rotation. Is this correct?
