Think we're lacking that buff now in most of our raids :s

Go recruit zabs priest as raider! then we got it!

Apparently the hunter Sporebat pet now also provides 5% spell haste.

Leading on from Hangen's original post here... http://raidcomp.mmo-champion.com/ is a nice little tool (i was using it to try and find the perfect 5 man group to dungeon crawl the first few levels with)...

Yea that has just been updated, it doesn't include the update to the hunter's sporebat though; All that has going for it sofar is a Ghostcrawler tweet and some comments on wowhead.

Can confirm that sporebats provide the spellhaste buff, went out to tame one on my hunter

we got atm 1 balance 1 trial balans 1 shadow priest trial and your looking for more haste buff O.o jeeez we are going to have meny buffs, i also tried the link bella showed with the people and classes we got and it all worked fine with what we had even tho we got a ton standbies in some possitions! but thats sorens move at the raid point..

and i can confirm Olimars provide +healing buff, i went out to tame one on my hunter
