Hello, i wrote two tickets on this topic and both times GM’s said it that i should post it here.
So I was on my alt DH farming the secret artifact appearance for the legion weapons and when i did it i came to realize that the recolors for doing the additional quests (200 world quests / 30 legion dungeons / 1000 pvp kills) were not shared and i have already done them on my main rogue. In comparison to this the achievement for the other hidden appearance “Balance of power” is account wide which again doesn’t make much sence. Why would one grindy ach be account wide but the other not? I think that would be a very good change if you make those account wide too mainly because there is no reason not to. Especially since now in the War within transmog items are shared across all characters and it would greatly fit into that philosophy if you may. Apart from Legion is a really old piece of content now and doing the achievements for that stuff multiple times doesn’t make the appearance look prestigious, it just makes it turbo painful. I would be very greatful if this minor change is implemented.
