There is some discussion about the value of mastery going on at the moment so I thought i’d put out a quick post rather than have my replay get lost in the comments on one of my other posts.
I’m tired so this will be blunt and hopefully coherent.
The base +20% shielding/+10% healing of mastery is a nice bonus. You don’t need to spend any item budget getting this. It’s basically free when you choose your specialisation.
At 80 mastery rating is great because we have nearly unlimited mana and more mastery directly results in more throughput. Players already have good crit and haste so they are seeing good additional throughout from mastery rating. So mastery looks good.
The healing environment at 85 will be quite different. We will probably have 50% more mana regen (i’ve made that number up) and we will have about 50% more mana in our mana pool, but spells will cost six times as much. Mana will be an issue. This is also the experiences of priests on the public test realm.
So the additional throughput of taking mastery rating on gear will be less valuable than most of the other stats at 85. This will probably change around patch 4.2 or 4.3 when mana regen is once again conquered and throughput becomes king again.
So that’s my take on it anyway. Discus.
