This Legacy Idea seems to be based around the notion of circumventing the need to develop a legacy.... unless it's only for Legacy capped players? Not to say that it's a bad idea (it does sound kinda cool), but the whole idea behind legacy is to encourage rolling alts, and hence, segregating those animations accordingly. A great idea, but I have trouble imagining BW implementing this idea for the reasons I've outlined. I do kind of hope I am wrong here.
I see your point. What if you were ONLY
able to unlock this feature if you had a level 50 of each Mirror Adv. Class.
