I've been told to upgrade my heal charm, and i've been meaning to for a while. My question is how important are heal charms? I play casters, but primarily just arena. (just wanted to clarify that i'm not a cata healer)

How many charms should I have? Do I need a full set, like damage charms? I'm just not sure how many are needed in a set to be more effective, besides obviously one for MQ ish levels.

Thanks.

well if u only Arena and not well u dont need a heal charm that much
but if u well whites u need a heal charm its the most important

It's despent how good your heal charm are (:

imo buy thoose level req : 15,25,35,45,55
i do it, and it works fine.
