Progging and clearing are different tbh
Like if someone join an intermediate relativity prog but does SB numbers that prevents their party from even clearing the door boss? They are not putting in the work expected for harder content and it's not toxic to remove them from the party based on that
Or if enrage is consistently being met with lots of percent left and there is someone obviously consistently underperforming, it's alright for people putting in the work to not want to play with them
