I was all for the pruning before the pre-patch. There are a lot of abilties, which most of my characters never use and they just fill on the actionbar. But i will say, that after the pruning has happend, that they have gone too far. Some specs/classes are missing situational spells, which gives them useability in some situations. For example, afflic warlocks have lost Rain of Fire, which was not a very good dps spell, but it made it so, that they could aoe very small mobs. Right now, as affflic, you are useless against creatures like the Dark Iron Recruits in BRD. The mobs don't have enough HP for your Seed to blow, so all you can do is dot them all and proberly die before killing half of a single pack.
Blizzard really needed to have a checklist nearby, when they did the prune, just to be sure, that they did not remove tools, which were life saving in some situations. Right now, i feel they did too much pruning and did not give enough back in the artifact weapen.
