On Clerical Wisdom

[envino]

So i started a cleric a few days back, and have managed to eek my way up to level 8. Im starting to wonder about wisdom - I know that my most important stat..

So far ive biased my gear acquisitions toward AC, im wearing a set of banded,with a few wis pieces. Ive managed to get my wis up to 137 while having the AC to reasonably melee solo.

Am I doing it wrong? I got in a group the other day and was just about useless as a healer, my best heal barely moved the tanks hp at all, and I was constantly out of mana.

So is it time to start stacking more wis and giving up on AC or should I maybe build 2 sets, a healing set and a solo set?

I guess im just not sure how wis works, how much is enough, will it make a huge difference on mana regen? Im pretty much useless as a healer right now without clarity.

Any suggestions?
