Losers always copy
I mean all of apac tried to copy Paper Rex agression. I've seen that on Team Secret ascent and they kinda lacked the firepower to do so. Every team in APAC who doesn't have agression to block rotations always loses the round.
Xerxia excels in Slow game and they are doing exactly that. If they did copy PRX like many APAC teams do they wouldn't be here.
