Granted, WotF is pretty sweet.
And for a time, I looked down on myself as a quasi-hordie for rolling a Blood Elf.
It may not be the best choice, but arcane torrent is pretty sweet. 2 sec AoE silence means having an extra kick on my hotbar and I don't even have to target the caster (if I'm not already).
Plus, some duel-rat showed me how arcane torrent brings enemies out of stealth. If you are engaged, think you will lose the opener, want to be annoying, pop AT. Its fun.
Base 5 resistance to nature + fire + ..... is nice too...
