I found out how evil aims vertically very well. His sensitivity helps but what I noticed is he likes to keep his xhair as horizontal as possible making it easier for him to hit harder from a vertical angle. I also found out rapha likes to make the mega and ra clash when he is over-stacked on armor sometimes even if he is out of control and/or the opponent knows so that he can deal damage at the major items while being able to take his own major item safely or the opponent can waste his time waiting for ra and if he decides to give up on ra then you can delay him so you can steal the mega. This works especially well on maps like battleforge where you can punish both major items easily without sacrificing a major or receiving lots of damage. t7 works too but it's harder to defend/delay if enemy gives up waiting on red. The more you know :)
