There is nothing wrong with an aggro style, but there IS a caveat that they seemed to have missed. In previous tournaments Paper Rex would play aggressively but back it up with good coordination and teamplay, which seems to be lacking recently. For example, against G2 there was multiple instances where someone just pushed out with no supporting util and gave away man advantage(also shown in their FK/FD ratio in that series). G2 were great at punishing reckless plays like this and that is a huge reason why they won.
