boomkins get typhoon (kinda like thunder storm), +6% more nature damage for the current target, 20% haste for 8s on crit (30s cooldown), roots, cyclone, trees, etc seems like pretty good synergy to me.

also if they do go thru with the 2 spec system (so you can just flip between 2 specs for free) then youve also scored yourself a tank in pve.
