Made a mage last night, and managed to get to level 6, but it's even more painful to level in WoW than it was before, after having played GW2. I'd have thought they'd put more effort into making the Pandaren starting area interesting, but besides looking nice (for WoW) it's still just a hugely boring grind, made even more boring thanks to the pitiful number of abilities you're given. I'm really just sick of every fight involving little more than spamming frostfire bolts, with the occasional fireblast thrown in.
To compare, I've got a level 6 guardian in GW2, that has 15 unique abilities, with just the skills for greatsword, 1h mace and shield unlocked (I didn't count the basic attacks on the weapons I have yet to fully unlock in that 15, as a lot of them are pretty similar. If I'd made use of more weapons in the time I've played, I'd have even more abilities).
Add to the lack of abilities the fact that I can't move while casting, and can't dodge attacks, or the complete lack of any challenge at all to the game's quests, and WoW is just really dull. Meanwhile some of the dynamic events in GW2 have been challenging enough that I've died several times levelling to 6 (along with everyone else attempting the event, several times over in one case).
