It is not an excuse to move on and add more content when old content is not working. If we follow that logic, IF 1.2 end game content is as buggy as EV is, would you accept the reasoning that they are working on 1.3 and to deal with it. Now im not saying that there isnt work arounds to these bugs but at the end of the day they are bugs and we have had ZERO communication as to when they are likely, if at all, to be fixed.
I hope the new content isnt as buggy as EV and hope that the devs have learned their lesson(s) in designing the new raid content and become more transparent with issues like these in future and not rely on the community to work around these issues for them.
