I like the idea, it would definitely make combat more interesting all around.
"This also kinda screws with rotations, doesn't it? In the interest of maintaining steady combat, the default attack will be redesigned to an auto-attack, freeing up (in some cases much-needed) space on action bars Damage from auto-attack may also need to be increased to compensate for the dps loss of dodging. Abilities would still function as they always have, and will only work if range permits."
I disagree with the auto attack, though. You make a great point with making combat more dynamic with dodges, but, IMO, putting the auto attack in makes it less dynamic. It should be a choice, whether to dogde or DPS. But that is just my opinion
