Is anyone at GGG looking into this matter ??

Constant disc in all map instances with rollback when fighting bosses including ToC, ToS and Pinacles , and the problem is that once you're disc from them they apear closed and you're removed from the instance...witch makes all endgame unplayable! Is there any point in playing endgame instances? will level a monk , lets hope you guys can resolve the matter till i hit endgame on monk...gettin tired of making new characters over and over again :/
