Had another free for all mecha brawl the other day. The YF21 gets really annoying... oh wait, a MAJOR ANNOYANCE.
3 players (including me), knows it's too darn cheesy and overpowered, and uses other valks. But the dude... just keeps waiting for the SP bar to fill up and "gulded" us in one fell swoop with a 38 kills to 5 deaths for the whole 10min round. Not fun.
Hope in the sequel (if they actually make one)... devs, FIX the ability!
