Vault nerf is cause of bad healers. Don't get me wrong the jump in damage from aery to vault is quite astonishing I levelled blm,sch and pld through that and as a sch I actually struggled a bit got through it every time but jesus the dmg tanks take even with up to date gear and then that last boss was a nightmare to heal. It was definitely a shock to the system first time healing that.

Vault is a small challenge but don't get me wrong I am a half assed healer and still got through it fine.
