I never have enough rage for execute on these bosses. I don't know if I'm doing something wrong but in these heroic dungeons the bosses usually die before I've had enough time to get more than 1 or two executes out. So my question is two fold
1. Should I be stock piling rage just before the execute phase?
2. If not what am I doing wrong?
I'm arms for dps btw. Strangely enough I don't have this problem as prot and at one point hit an 800k execute on Sha of Anger. It's retarded, execute is so strong I love it. I just wish I could use it more
