Tbh mana regen have been out of control for way to long, before tbc people actually took a look on theyr mana bars and healed smarter.

Blizzard have to take most of the blame thought.

Taking away downranking most likley killed most of the uniqe ways of healing.

Now EVERYONE use the same spec,rotation,buffs,gear,talents.

Everything that once were uniqe is now gone.

WOW you finally got that deadly gladiator pice, well grats there are 200k others who got it just the same way. Same spec,rotation,buffs,gear,talents and even the same class for arena partner. Even they share the same spec etc etc etc...
