I know not the usual kind of thread(not sure if ok?).... but applies to a ton of us playing WD. I'm surprised they didn't fix this today --> here is the place to post to get it on their agenda. I'm surprised barbarian shout glyph stacking was fixed over this unless it's for a programming reason. Fixing this still isn't on their "known bugs"list.
