I noticed the correlation between Pulverize, Mangle, and Lacerate feels rather off. Currently it seems as though most of my Global Cooldowns are devoted to keeping Lacerate up, just to take it off again and start over. The proc relationship with the Mangle cooldown seems fine, but still it's just another GCD to burn while getting your Lacerate back up. It almost feels like the old Savage Roar mechanic come back in a way.
In short, skill order for bears just feels rather awkward. Perhaps the intention is that it doesn't come to its own until 85. But I'm re-leveling all of the tanking classes at the moment, and Paladins seem to have a great feel to them by mid 30s.
Just a discussion of mechanics, not OP or UP.
