I honestly don't think he's aimfixing or shotbotting,

for aimfix;
He technically doesn't have any obvious miss that registers as a hit,
he once shot totally miss on my screen, but still trailing the movement of the person he shot at (usually due spike/lagg), not really out of the ordinary.

for shotbot;
The moments you stated that he blocks a lot, actually were moments he were at your base, he never really did it at his own base, as I conclude this is just strategy, also no weird slashing or shooting.


No from me.
I'll await the opinions of other gm's.
