If you want expansive skill tree, Path of Exiles (but its an Action RPG like Diablo, not an MMO). It's also F2P. It's been called many times the game Diablo 3 should have been.
With its skill tree (designed like FFX) you can create a lot of different types of characters like you could in Diablo 2: LOD with its combination of runeword items. Although I got bored of Path of Exiles. I kinda like the idea of starting up new characters but never finishing them haha.
Mists of Pandaria for me atm is slowing down because of all the no item drops from pretty much everything: world bosses, heroics, and LFRs. Then there is the ridiculous faction rep grind that you can only get through daily quests per faction (takes hours to do, just stopped doing them all together). I started playing on my instant level 80 character to get to level 90 with. Hit level 85 last week, but not so interested in the ~35 hrs needed to do 85-90.
