Christ, crying about nerfs in a beta... It's far from finished! God knows what they'll do with the talents before releasing Wotlk. Just quit the freaking whining about stuff that isn't even live yet and of which you haven't even seen the final version. Blizz is still trying stuff out, nerfing this, buffing that. Sometimes the same spells get buffed/nerfed a few times in a row. Maybe Arcane Barrage will be completely overpowered when wotlk comes out. And they'll get a nerfbat thrown at them like feral druids when TBC was released.
