In regards to the third point, yes, having the Pulverize buff during berserk increases the threat generated by each Mangle, but if I spend a GCD using Pulverise to refresh the buff, then that's one less Mangle I've used during the Berserk time, so I'm looking to see whether maintaining the crit buff from Pulverise at the cost of this extra Mangle will generate more threat than just spamming Mangle and having the last half of the Berserk Mangles not be buffed by Pulverise.
