Even if they fix it. Face it. You will be a mana battery in all long and hard fight.
If the healer run out of mana. They mst be re-filled. Or your raid will wipe.
But I don,t understand why its not the Necro or the Conjuror that is the mana battery. At leats they can trow their pet. So they were not jst beeing mana batery in EQ1. They were also. Doing some little dmg.
Your only hope is that SoE give the mana battery job to another class. otherwise, you'll stay the mana battery.
P.S.
if w speak about Raid.
Warlock are DPS.
Wizard are utility.
If they would be both the same. Why making 2 class ?
