Pretty similar to my post here.
It’s exactly as you said. If the wizard dies too easily or too early, the round is a boring greenshift. If the wizard just demolishes all of Sec, the round takes forever to truly end cause the wizard is holding the reins.
I think a lot of this stems from roundstart wizard being the only antagonist. If there were more antags, greenshift wizard rounds wouldn’t be as likely. On the flipside, more antags means more people with the tools to oppose the wizard.
Another issue is the complete lack of spells. You see the same spells every shift because those are the only ones worth taking. Have you ever seen a single wizard take the spider polymorph and it not be by accident? IMO the wizard needs a few more spells in the major categories: offensive, defensive, and utility. Where the wizard needs a LOT more spells is in the silly category. We need the ability to turn the wizard into a super clown. What’s more disruptive than a clown with magic?
I am also of the opinion that Wizards should be handled under space law like normal. If they fireball a single person? Murder. If they fireball the whole station? Mass Murder. You will still end up executing murderbone wizard, so nothing changes there. What this does change is carve out a space for the Wizard to skirt the line with how antagonistic they can be without the guarentee they’ll be round removed if they get arrested. I feel like a lot of wizards go murderbone route because it’s highly likely they get killed on sight anyway, so they might as well have some fun and blow everyone up.
