I totally plan on watching this weekend. Both are oppressed groups. The damage increase per stack remains the same, at 15%. Only the aion kinah cost has changed, and it has actually gone down. Instead of doubling with every stack, it has gone back to something closer to the pre to Wrath era to to 130%. This means that the mana cost per stack now looks like this.
I was going to bemoan such things as Arcanes inadequate DPS, PvP survivability, and overall mana inefficiency. It was going to be overly to dramatic and incredibly whiny. Warlocks were going to drink from the well of my tears, and find them delicious.
While Greythok happens to be on a server where I do not have access to them about aion kinah, it is likely many players considering a shaman alt for the first time will have access. Patch 3.2 created more options for leveling with Heriloom Chests and several new Heirloom Weapons.
