I witnessed server 5 receive runes when the cap was raised for thay server at 85. Server six was given runes at cap raise level 70. Server 7 is currently at cap 80 (which did occur 2 to 3 weeks ago, there have been steady 5 level cap increases monthly) I personally am expecting runes to be released with the cap raise to 85 (please be soon)
Edit: if you look at patch notes for 2.6 update (august 25th) the server 7 cap was set to 75. And we received the update 2 weeks ago witch raised cap to 80 between august 25th and now. So safe to assume that was about 2 to 3 weeks. Hope that settles that argument.
