Whatever you think of the latest forum drama, I can remember that people have been rage posting on the world of warcraft forums since before the game even came out. People used to viscerally complain about class imbalance, faction imbalance, ganking (back in the day realm forums were big), high end raiding guilds, casual players, legendary items, etc, and now streamers.
I think everyone should remember probably less than 1% of the player base posts on the forums or even cares enough to read it. Dont take it too seriously!
