Pretty cool to see a revival thread of this game.
I've been playing RotMG off and on myself. I currently have a 6/8 priest and wizard, but it's been a slow process attempting to 2k them both.
I've actually gotten so infuriated about dying the numerous times I have, that I've started compiling a mental list of "anti-tryhard" classes I want to just straight up get 2k fame on so I can get white star, meaning that I'll try to max them to a decent point, then just sit in a godtrain.
