You're an awful paladin then and playing the class completely wrong.

Even for AoE pulls you only need to do flash so often. And in single target boss encounters Flash should literally be used only if you're completely out of TP.

I mean, honestly. At least spam Rage of Halone instead of Flash so you do some damage, you're basically doing the equivilent of a BLM who only uses Scathe or Ice I.
