This is a great addon, please come and update it. I was excited when it was available for beta, and i think it could be huge with the wow community if it was updated and a few things were fixed.
i use this mainly on my tanks b/c they have rolling defensive abilities to keep up. such as pulverize on my druid tank, i can keep this ability applied to myself 100% of the time without losing any dps! works wonders not having to watch a buff timer. Also on my paladin tank i can keep holy shield applied without wasting a gcd on reapplying before i need to, and it's also very handy seeing my shield of the righteous buff.
Come back to us !!!
