So I have a message every time i would like to enter Naxx, on Frostmourne server. I was the first to get tehre, we had to set the raid ro 25 man, so i had to go out and in, then i was going out and in because of summons, and now i have this message: You have entered too many instances lately.
There's an instance limit of 5 per hour. For example, if you enter once and then wait 30mins and enter 4 more times then you would have to wait 30mins to enter again.
sort of sliding window from first, I believe meaningful entrance into an instance (as in, interacted with something inside like picked a herb, killed a mob, possibly stayed inside for 60 seconds)
if you enter dungeons at:
16:36, 16:47, 16:56, 17:13, 17:20,
then you can't enter the next one until 17:36 when an hour has passed since the first time you entered a dungeon, after that 17:47 and so on
