So, any dps on a leg is basically the same thing as hitting the boss for twice the damage.
Now, of course ranged classes can't really afford to be moving around, so they're out. But basically every other melee class should be on them, "cleave" or not. There's no reason not to, and it's a DPS loss for them.
It really comes down to everyone trying their hardest to keep up optimal rotations for the whole fight. And keep killing legs all the way to about 4% or so.
