Quote from tennbergIt's not a game bug AFAIK. I believe it was done by Blizzard to prevent people in pugs who had an assist from spamming the raid with ready checks.
I dont think that is true, was RL tonight, one of my officers could do Ready Checks and one couldn't and both were promoted, so i believe it is an add-on error.
The only difference was one got his add-ons from here, the same as myself and we could both do ready checks. But meh just thinking things which probably have no bearing on the issue.
