So... The Developers hinted at changing Berserker Stance to Battle Stance (10% damage to Battle Stance), and making Berserker an AoE stance (20% increased WW and Cleave damage). They also said that stance requirements for absolutely everything is being removed.
Personally, I think this is pretty stupid.
Lose 10% of all damage to gain 20% damage on TWO abilities (one that has incredibly weak damage)?
Dumb.
Since Death Knights are Warriors but better, why not give Battle Stance something similar to Unholy Presence and Frost Presence to Berserker Stance. It fits the class philosophies pretty well.
The Berserker, hitting really hard with lots of rage (instead of runic power), and a standard Warrior in Battle Stance hitting really quickly, moving around the battlefield quickly. It says right on our specialization tree that Arms utilizes mobility, why can't we have that? We're also the only melee class that doesn't have a built-in 15% movement speed increase.
That, or just remove stances entirely and give us a static damage increase. Bake the passive threat increase in Defensive Stance into Sentinel.
Out-dated mechanic.
