I see an aimbotter.
The way he shoots those dretches in the first demo, sorry, that ain't real, no way.
In the second demo, well, why in all world does he fire at the lower part of the wall, and a second later it turns out that a basi was here. There is no way he could have “seen” this except for his aimbot leading his aim.
So, if this does not have already happened, some time off would be a good idea for him.
