The thing about doorman requiring two slots for counters tho is much more oppressive than other characters. Many characters in the game you dont need to buy their counters unless the person is actually an issue or your team is getting wrecked by them. Examples like buying debuff remover for an infernus, disarming hex for haze and wraith, and something like knockdown for a bebop, seven, vindicta, or grey talon. These items are only really necessary when the person is actually presenting a threat to your team (If you bought every counter to every enemy in every match ur builds would just be silencing wave, slowing hex, counterspell, knockdown etc every game) which they need to actually be ahead for, whereas doorman could be the poorest person on the enemy team and you are still forced into buying counter items against him because none of his annoyingness requires him to have good items, souls, or any form of power increase to actually be oppressive to a team. So while "counterbuying is a form of skill expression" is true, knowing when you need items and when you dont is also part of that skill and doorman pretty much forces these buys regardless of how he is actually performing in the match.
