Gnomes only give 5% extra mana pool, not 5% extra int. Obviously it would be hard to beat a racial that's +250 spell power. Gnome isn't really an option, except for PvP.

Worgens also have 1% increased crit chance. That's nothing spectacular, but that's never lost either.

It's funny to realize that Dwarfs, that were the clear best choice for Alliance priest are now the worst choice (frost resistance and stone forme (bleed, disease and poison removal, 2 min cd) are the only useful racials for Dwarf priest. Others are gun (lol) and mace (relol) specialization, and the archeology bonus). Nightelves are not really better, with quickness (2% dodge chances on physical attacks), nature resistance, spirit form for rez and the fake feign death. Nothing really useful, but nothing absolutely definitely useless like guns or mace specialization. Draenei are a little bit better, because their free heal on 3 min CD off-GCD at least brings something. Except this and their shadow resistance, nothing useful either.

New thread for Cataclysm is up.
