Wizard is a bad mode for MRP. The antag is very clearly designed for LRP with how most of it’s arsenal includes murderboney weaponry and extremly chaotic spells like summon guns or summon events. The antag is clearly not fun for anyone but the wizard on MRP. Even with a 1% chance, the antag can happen multiple times in a row (See todays test, we had 2 wizard rounds almost back to back).
That’s why I think it should be disabled, it just aint a good fit for a MRP server.
EDIT:
Wizard also encourages not doing patrol, as if there’s a wizard the round will probably end quite soon anyways and you won’t be able to do any patroling.
