here is a link for the vuhdo setuphttp://vuhdoguide.blogspot.com/2011/...gh.html#GenInd look for the custom buff/debuff tracking. perhaps it will allow you to set that up.

I don't count stacks myself, I just look for the orb circling me and do one of two things:

1) i have a repeater region setup over the buff watch frame which is setup for all my shamans to cast their shield. since i'm always looking at the tank i can see earth shield is no longer circling him, and recast. Sure this way i might be rebuffing someone else prematurely, but it works.
2) my main dps key is '2', that's everyone but the healer. on '3' i have everyone dps and the healer does a cast sequence for riptide, earthshield and a couple of other heals directed at the tank.

i tend to use #2 the most as no one skips a beat in their sequence, frees up my mouse for other stuff and ensures i'm getting those spells on the tank.

hope that gives you an option you haven't tried and best of luck
