Take out Ready check? are you being serious?
I Understand that with a new feature (in this game) people are going to see how it works and "play with it." But get real, if you are a raid leader you should love a ready check. If you are among the majority of raiders that do NOT read minds and have to deal with people that for what ever reason are not on your voice server, a ready check feature is extremely helpful. If they limit its use to a raid leader then should should be no way to "abuse" it as you complain about.

Most useless feature? hardly, try the making me look wet in the rain feature for that claim.
