Blues playerbase is actually way more toxic, it's just hard to figure that out because of all the forum cleansing and PR work done from the staff.
Their raid scene is also complete shit. I was a part of it before this server existed. It's even worse now with velious. For more insight on how bad it truly is just listen to the first 10 seconds of this video:

And that's just for a regular mob, not a raid target.
The only reason red gets a bad reputation and neglect is because Rogean actively hates this box and goes out of his way to make playing here awful. Can't really blame him though, he makes a lot more money off blue.
