This is an open letter to please stop spending time on controversial fixes for now. Spend your time working on advancing this game and saving it from dying. I sincerely doubt people are leaving the game in boatloads because you can /death in a quest or 4-man a raid mission. This may be debatable but I doubt you're going to see many exit surveys with "game too exploitable" in the comments.
I can, however, guarantee you that unless you start getting serious with your pro-active and long-term development of this game, there won't be many left.
I'm not saying don't fix those things. I'm saying can you please put them off until you have a handle on the future of this game. Priorities are clearly, clearly out of whack. 3 content updates late (in a row) and we already know the next module will be late. So please, enough of the fixes that you have to un-do or alter (see raid loot compromise) thereby wasting MORE of your time. Spend your time on things that are going to pave the way for growth in this game.
