Not only the animation but I'd love it if the effect of wildfire was changed so that if you killed the mob that had wildfire on it, it would spread (get it?) to all other mobs in range. It feels like a real waste when the mob dies before wildfire goes off and basically makes it so I rarely use it on trash pulls. If it spread to all other targets if the target died it would be a good way to do some pretty good AoE damage on trash.

Wildfire your primary target, AoE and use your single target oGCD's on the primary one, if it dies the wildfire spreads to everything else and goes off.
