Classic which server should I play on?

I am a returning player but never got a character to max level. I want to come back and I am interested in eventually doing end game raids and such but also want to play pvp. I like there to be a high population. The idea of playing a RP server that also does pvp seems cool too. I would like there to not be a huge difference in faction population for the reason that I don't want super long que times for pvp. via /r/wow https://ift.tt/DXcRfY2
