Make priests lightwell worth to pick up pretty please, we like our wells!

So basically Lightwell is not used atm at all, i used it because i rly like the idea of the spell, its like a totem for us.
but sadly you dont wanna take it because you lose 10% less mana usage from your prayer heals.
I would "fix" it to be something like 10 stacks and like a renew spell . so it wont wear off when you take dmg like you do atm.
6 min cd for 5 charges is pretty weak of a well isnt it? it should be renamed bowl of cereal instead of well :D

What you want to do ( and from experienced TBC Holy priest raiding ), Is find a few really good warlock friends, keep them in private whispers or someway to talk to them easily during a raid encounter ( without bugging everyone else ) Put Lightwell next to said warlock or warlocks, keeping in mind you explained when you were gonna use it etc.. work out the kinks. It takes a bit more micro and forcing targets to accept it. In some rare circumstances with an over stubborn Damage Dealer, I'll announce " either you touch lightwell or you die " , oh you bet they are gonna tag that well.
