I know a bit about roccat too as I've spectated a lot of cheaters as well...
As mirko said, this video doesn't prove anything at all.
He shot 3 or 4 times before hitting once, and as you said, dr uses promod scopes... Which I always found are incredibly easy to land noscopes with (that's a reason why I dislike them).
This clip looks like 80% of what's happening in dr scope rooms, I don't know why but somehow people like to do no scopes and apparently even feel kinda proud about it while it even requires less skill than hardscope (I'm not talking about quick scopes, only no scopes).
Anyway, if he is using it as often as you are saying it, and if so many people saw it, I think more should have been recorded, don't you think? He is a TRUSTED player, and you're banning him without even giving a notice to admins on forums, and without even recording some solid (or even acceptable) proof? Really?
Genz is a trusted player as well, you're telling us we should believe trusted players, well then we should believe Genz as well, looks like it's not possible to believe everyone here.
I don't know who is right or wrong, I just know people like shitting on each other faces on the dr server, fighting over perms and shit, look how badass I am I can insult you all day idc I'm trusted, I can kick your ass and ban you if I want, so fuck off, I'm right and you're wrong. What a fun server it must be to play on it these days really.
