My friendlist has 180 people on it. Probably a mix of 30 irl friends and 150 wow friends. 77 is currently online. Only 1 person is playing a battle.net game, and that is hearhstone. On better hours, I usually see 10 people in battle.net games, mostly cod or wow classic. Sometimes there will be 1 or 2 guys playing D3 or HS. I never see anyone playing retail.
Its honestly kinda sad looking at the battle.net friends list. I dont really look at it nowadays. It used to be so alive but pretty much everyone I know quit WoW.
