Insanely decked players who have every item in the game but don't do runs - got everything you need? Improve your run times.

FOmar's (You wanna be good at melee? make a HU! You wanna be good at techs? make a FOnewm/FOney!) - this one is just a joke
DFlow spam on anything and everything, control that wave silver surfer, don't blind me brah!
