I hear different things about where the average renown rank of players is right now. I read that most people are already RR80 or that most people will be RR80 very soon, and even that most people will never reach RR80. So I had to find out for myself.
The Realm WAR page for Europe was recently restored to a place where it works so I could look up Destro that appeared in my combat logs.
Below is the RR distribution of 100 random Destro I have fought on Karak Norn. There will be some error from only taking 100 ppl, and some will be alts, but it gives a good indication of where it's at.
On Karak Norn most people are already RR60+, most people will soon be RR70+ and it looks like most people will get to RR80 one day (me included!)
