Thing is...they can't ban all ppl who did it..because they cant have in their logs all people who did it.. they can only ban those people who got reported with videos and ****...
My opinion again... don't use it too much.. i mean you can increase it to some 300% attak speed and that is still good.. but people wont be too suspicious about it
...
I always use it with 5000000% speed xD but thats just me :P ( but not on my main tho)
Also dont forget that there are many rangers out there with their invisibility buff ... and all they do is record every **** all day long in order to get you banned... it happened in CM ..it can happen here too
