I really think the room creator should be permanently Opped. So if you op someone they don't rage and deoperate you and add a ban you.

Yes please! If you give OP to a troll then they will just deopp everybody and you can't do much. I think there is a /set owner command but that never works for me.

The /setowner command does not work. After they Deop you they would change that command before you can op yourself back. Nice point you came up with

Especially for clan wars where both clans must be opped.

Yeah, some friends of mine have had cases where the other clan will abuse their op or ban the other team once they win/lose.

I can already tell that by checking the general support section....

I've had my server stolen before. Not good. Supported.

Why would you give op to players who you can't trust?

Because you have to in a clan war, one time my server got taken over after a war because we had to op them.
~supported

You have to OP someone in the other clan in clan war. They might rage and kick :/ and what's the point of OP when other op can deop the person who opped them.

who says you have to op someone from the other clan in a clan war?
