He probably said it cause you kept afking and leaving and the team having to play a 4v5. It might have been better of with Ras playing. He didn't do it as an admin, just as a player cause he probably wanted to play a proper 5v5 without people leaving.

About questioning admins, you are free to. Ask him why, ask him for what but don't go around disrespecting an admin. It's all in the rules.

My general rule of thumb: you don't have to give your spot back but you can be a nice guy and give it back. I almost never use my admin to ask someone to give their spot back.
