Problem here is input lag no lag compensation and awarding people with the worst connection. Of course it feels cancerous under such conditions. If the game was coded only slightly different and with time snap back in place, it would not be as bad.
However, in a time with kensei teleport instant dodge attacks due to bad connection, everything fast ist unbeatable.

With a good connection on both sides thought blocking top really helps. Just leave your block there and counter after you forced him to stop. Besides with the first hit almost always being a light, you can go for a parry and heavily punish the Aramusha. It's not like he has anything else.
Shaman beats the crap out of him any time of the day.
