Thanks for the feedback guys. I heard about Holy spamming, and I KNEW I wasn't casting it enough. I was excited to get it to give me something to cast along with Stone II, and then freaked out when I saw the MP cost. I immediately began having thoughts of being responsible for a wipe because I casted it too much and ran out of MP.

I guess I was also very comfortable with my MP management and DPS output prior to getting Holy. It's like it took 45 levels to finally establish some confidence and stance dance like a champ, and now I just have to adjust to the new ability. I understand this will come with time and experience, and mistakes are going to happen. It's exactly why I prefer to level very slowly. I will definitely begin to cast it more. I feel I can be a little more spammy with it during trash pulls, but really need to be mindful during boss encounters.
