It is already done as I can see on the leaderboards,and I think this is the right way to do it!So,thank you!
About individual runs,I also think it's ABSOLUTELY mandatory to have pre/post patch categories!I thought that is a no brainer!Without that our world records before the patch,that we worked so hard on,will be deleted?!Now,if that happens I will probably lose any will to speedrun in the future!Btw I am an Xbox One user as well! I mean,would't it be more reasonable to have two major categories:pre patch and post patch,and then all the sub ones:glitchless and non glitchless etc.?I know Xbox users(as myself)are forced to submit only post patch runs but we have to accept that,there is nothing we can do about it.HOWEVER our pre patch runs HAVE TO STAY,NO MATTER WHAT! And if someone wants to beat them they are free to do so by downpatching.This way pre-patch runs will still be alive and legit!
