The crap dervy posted can really burn in hell. If I want to only DPS, I play a DPS class and that's the end of it. I like to DPS when the group allows it no matter the content but what ultimately makes you a good healer is not having the perfect stats.

If you can't assess situations, don't have the ability to know when to precast or generally don't care about keeping your party alive - you have the wrong profession.

I main whm and while I play other healers for fun, I don't touch them for raids/extremes. Especially because of the high mana consumption and enbding up solo healing more often than not, I always make sure to meld Piety where I can. Having 100 points more healing doesn't help me if I don't have the mana to cast it.

My meld strategy would me: PIE>SS>CRIT>DET

I don't care about ACC since any DPS I put in is an extra and will not be counted as my main priority.
