I will post this in both the tank and healer forums to get different sides of an opinion. I am of a mindset of have and not need than need and not have. I know that both WHM and SCH could always pop it before big fights and better MP pools for it's use but there might be some scenario that comes up where having that option could help. So Is it really worth it for me to level my CNJ (only lvl 21 now and not looking forward to grinding to 34) to get Stoneskin?
