Riot, have you thought of making Camille's ultimate go away if she dies?
Apart from the W healing on minions (which Riot is addressing in patch 7.7), this is the big thing that I despise about Camille. The ult walls should drop if she does; it makes no sense if it stays up after she dies, seeing as it is supposed to be an ability to 1v1. In a typical 1v1, there isn't a problem with the ultimate in my opinion. In a teamfight or when one gets caught out, then I am pretty annoyed. Yes, Riot did additionally nerf the duration of the ultimate at lower ranks, but the big issue is how it will keep a carry trapped in a confined area for 4 seconds come late game, so long as Camille lands her ult on the target, which isn't necessarily hard to do.
This isn't QQing, I actually love the champion and she is deceptively fun, yet that ultimate is just so anti-fun to play around.
Edit: I am aware of the current nerfs on the PBE (soon to be on live). I feel this change would be worth looking at if the current nerfs are unsuccessful in some way (too much or too little).
