I fail to see what people mean by potential. Could someone describe to me what wizard actually brings to the table? I have never, in my six years of playing SS13, experienced a wizard round where I walked away feeling like I didn't waste 2+ hours of my life.
First off, wizard's tone is abominably unfitting. Someone will say "But we have other magical gamemodes!", and my counterpoint is that our other magical gamemodes are a lot darker in tone. Cult, vampire, whatever - they're not jovial blue men in robes. Do you compare Vampire: The Masquerade or Darkest Dungeon to Wizard 101 or Harry Potter?
The best example of how out of place wizard feels is to bring up The Wizard Federation, which is an entity some wizards love to reference. I don't know why wizards have a nation-state, but apparently they do.
As far as gamemode and gimmick variety is concerned - All you have are your spells. You could do some gimmick involving recruiting people to be wizards as well, but if anything this is just another example of how wizard is an LRP gamemode - Who aboard our high-tech research station, in their right mind, would sign a magical contract and start gallivanting around in bright blue robes while declaring themselves apprentices of the Great and Powerful Jhon Jhonson The Black?
Furthermore, if wizards DO have some fascinating RP-stimulating potential I'm incapable of seeing, it still means nothing. You know why? Because nobody ever uses it. Having "potential" that is just wasted by every single wizard player is not enough of a reason to keep a nonsense gamemode in. As far as I'm concerned, having wasted potential is a reason to remove it in the first place - it's wasted for a reason, typically.
Wizard is a gamemode that is only fun for the person playing wizard, the vast majority of the time. I understand people are afraid of losing variety, but let me give you an analogy: You're in elementary school again, and the school rotates five different meals for lunch. Four of these meals are good. The fifth is a pile of literal dogshit. Would we be depriving the school lunch menu of variety by removing the dogshit from the menu? Yes, we would.
