Thanks for opinions guys
@ those of you who say "forums are already cluttered enough" "no need to waste space" "wow is dead" (wow that meme has been going on for over 13 years now) - this really wouldn't be noticeable unless you look for it
It would also be really good to avoid confusions, just like RS trading / oldschool trading has different forums, POE has different forums for every league, Guild Wars has different sections for GW 1&2 within the same subforum, and of course Diablo 2 has Ladder/Nonladder/Classic and Diablo 3 has seasonal/regular/console tradings
We can argue all day about how much activity is needed in order for people to care about the subforum, point is there WILL be more activity come Classic release and this wouldn't affect anyone except those who actually visit the wow subforum itself
