5 boomkin?

[algol]

-new 51-pt AOE dot talent, talented to have a chance to stun

Starfall + Celestial Focus.

The chance is 15%...I expect it's "15% over the duration of the spell" a la the warlock hellfire stun or mage blizzard chill effects. But even then, 5x moonkin casting talented Starfall gives you an (1 - (0.85^5)) = 55.6% chance to stun for 3 sec per target. While doing rather substantial damage. Definately amusing. The "max 20 hits" and "buff on caster" aspects of the spell means it may be per tick and not total chance over a completed channel.

And yes, stealth runs are giggles.

For PVP, I imagine you would make one be a Treekin instead, then it's largely a variation on the Xzin method but with the OOM looming more heavily.
