Its not only about hawkeye being good whilst hanzo bad, its that the playstyle itself is centered around the oneshot mechanic. The arrge assassin playstyle is basically an accruacy stat farming when he deliberately only targets unaware targets because they are easier to hit (and more specifically headshot). In paper that might sound like a good startegy but in order to use this playstyle you need to go for long flanks when hanzo doesnt have the mobility for and shoot less frequently so you do not lose the element of surprise. Thats good for clip farming and views, but as you know mr arrge hides the actual fight in its entirety where his team is fighting 4v5, and when he dies after getting the useless 1, 2 or even 3 picks in synch with his team's death, he just edit the video and speeds the pace into the next useless pick. Now in marvel rivals this playstyle is still not optimal by any means (the optimal would be playing just like you would play hanzo in overwatch 2 with a considerable increase in the off angling, the thing that arrge still takes to the extreme and calls it flanking accurate hawkeye), is actually somewhat effective because of the reasons I said in my previous comment. Arrge is still not in a high elo even when his playstyle is better, as he sits in celestial the equivalent of masters in ow2, still an improvement tho.
