SpaceCadet I just wish the admins were more experienced in the scene so they can identify all the proper players who need to be restricted.
None of the restrictions come out of nowhere, they have statistical backing from logs, league experience, etc. We don't pull class restrictions out of our ass, we genuinely do a lot of research and investigation to try and validate every restriction we can. Most of the admins are involved in class restriction, a lot of times, admins with lower experience levels know better about players in lower divisions than say I would (the same affect in reverse for higher divisions). We also assist each other in looking at the logs/experiences of players when we are having a hard time deciding whether or not a player should be restricted. Sometimes we miss details and that leads to us overlooking some restrictions or being a bit too harsh. To be clear, restrictions are not set in stone and can be contested, and we acknowledge we are not perfect. I have on several occasions over the past year removed restrictions that were too harsh, or tried to work with a team to find the best situation for league stability and their enjoyment. Additionally, sometimes personal bias can really sway class restrictions in a bad way, so we try to stay as objective as possible.
TL;DR The admin staff has plenty of experience and support around them to make restrictions, they are not always absolute, and they don't just come from nowhere.
FactsMachineWhy are people restricted off engineer?
Invite/adv HL players often get restricted in lower divs off their main classes. This is mostly to prevent invite pyros, snipers, etc. from tearing up a division on those classes. I've witnessed IM/AM players get torn through by invite HL players on their respective mains, so for consistency and balance sake, HL experience can translate into a 6s class restrict.
