I would love this, although duel servers are kinda already like that (In the sense of freedom).
Create a separate Duel server (Non strat server) That allows all items.
(only 1x multi at all times???)
I'm not so sure about this one. I mean, at least in duel you are learning how to fight (For the most part)
I think maybe a 1x multiplier with a longer tick would be fine.
I could care less either way, but its my opinion.
PS: Although I like this idea, since this is a bug. They probably don't want a server dedicated to people fucking around with it, cause then more people will know how to do it, thus, increasing the susceptibility to grieving.
