Hm..looks like you don't know how to read either.
1) The MP cost thing is just way too high
2) Con has access to 4 raises, so why can't we use them?
3) I didn't want CON to be a healer, but since it obviously is now, why can't it use the full extent of it's abilities?
4) Mages got the short end of the stick this time whether you believe it or not. At least other jobs will actually be able to use their AA =)
and yes, I'm very mad at the horrible imbalance in this game.
