lol what is that there for?

Im guessing its there for lulz
Wait... thats the talent tree for WotLK right?
Damn im gonna go check it out

yeah and its a direct screenshot from the one hosted on the main site

There's been leaked ones for quite a while, and earlier this week the NDA was lifted, allowing sites to post what they all knew from alpha testers, as well as the beta beginning. Blizzard also posted one themselves on their site, though it suffers from being out of date compared to the one from, say, WoWHead, for instance.

That icon is the prevailing "Placeholder" icon that has been in use throughout Blizzard software for years. The talent itself buffs a few of the druid's wind-based spells.

ahh i see so its just a placeholder. but wouldnt it be hilarious if they accidentally encoded it into the game =-D

They use that icon for when they don't have a set icon for a spell.

With my scroll combat text for example, when a shaman's searing totem hits me, the icon next to the number of damage is the head of that man.
