What kind of PU does Brook need to get from struggling against Sheepshead and getting no diffed by Peros while being in 2vs1 situation - to actualy beating a guy of this caliber alone?...
Who's who is talking about taking down a YC - if he can do it or not, we have to wait and see - but the fact that he is confident in his strength and a F6, shows that he is in the higher Veteran league or even in the YC league (unless he is overrestimating himself - have to wait and see).
PU or not, Brook is not gonna jump to that level.
