I've had a little bit of trouble with BM on a few fights, (Ore, Kromog during hand phase) to name a few. For example Oregorger, during the roll phase while dps'ing crates and one dies the pet takes off back to the boss and spends a lot of time running back and forth not doing much of anything. Any tips or suggestions to minimize dps loss during occasions such as these?

Hi, I have been trying to prepare for the switch to BM for 6.1 since that seems to be the new "go to" spec, but i'm a little confused on how/when to use Focus Fire. Do I wait for the 5 stacks of frenzy to use Focus Fire, or refresh it as soon as the buff falls off even if it is only at 1 or 2 stacks?
