Hi guys, die hard arms warrior here :-) I have a question regarding the 2-pcs rotation with CS up. if I'm at 70-80 rage, is Mortal strike still prior to slam/overpower? I only see MS as a rage-generator, not a big hitting ability. As far as I know, MS doesnt hit harder than slam/OP? I find it a bit confusing :-)

K, I will. thx
