AST MP Issue?

[Ninimo_Babamo]

Their healing spells are cheaper than most of the healing spells the other healing classes similarly use, plus you have a biggest MP pool. I normally don't have MP issues as long as nothing goes seriously wrong (and for a long time at that), like a pull doing too much damage or when the team is failing to evade avoidable damage.

Your AST isn't even 60 yet, and the OP is 60 and farming end game content. I have no idea why you think AST MP pools are larger. I'm i180 on both WHM and AST. Out of party, 10376 HP on both; 13027 MP on both. There's no difference.
