Yeah, they never finished the system, and made the power regen one super rare, so people stopped bothering except for mana intensive raids.
Anyone else ever play Channeler? My Sarnak Channeler was a favorite MMO char of mine. The heat mechanic was neat, and yeah the class was almost too good because they had to adjust raids for the flat % damage reduction.
I had a blast collecting up all the raid DPS gear that was leftover, and eventually got the rare healer ring that neutered your heals but increased your damage by like 50%. I would sometimes parse #1 on AE fights when I didn't need to heal. I would nuke harder than wizards for single pull, but the heat mechanic balanced that out quick lol
EQ2 was flawed but fun with the right crowd.
