I am noticing a small delay, so comparing it with the report which lead Chainzrow in a ban couple months ago I believe that he can achieve that without doing the known trick. Back then he got caught exitting the stealth at exact same moment with all his rogues and then using "Fan of Knives" simultaneously.
As you yourself quoted my reply on the last report, administration never setted a minimum time where we should ban violators but we decided that we must not allow players doing simultaneous moves or at least in an extremely short period of time.
Declined
