notice how this form has now changed? it's back to classic days...it ony gives armor now .. and the improved talent is necessary for the 6% crit aura.
however with 2 boomkins in the raid only one needs to be in Boomkin form.
To be honest, i'd have preferred the aura to be passive also.. and boommkin form have some utility spells unique to it.
So it is looking like you're not going to have to be in that form constantly. i don't like Furor providing 10% intellect in moonkin form because you lose it when multi-switching which you will do in pvp alot.
