This only really applies to clans with their own server but if they know the other team have a lot of players who are very good with mini whats to stop them from nerfing it, or on the other hand u know ur good with mini then u can raise it. Its not ur server so its hard to complain and how do u put rules in place to combat that? thats why imo configurable is bad for league use.
However as Timo said this is basically a public or test version and not, nor will it ever be league valid that point is mute.
Well, my impression was that once a certain profile is found to be the most satisfactory, it would be approved for official use in league matches; why are your saying this will never get approved for league matches, doesn't that almost offset the whole point of all this work?
As far as the mutator itself, I think if we end up with 2-3 final profiles as alternatives, I am guessing they could be hardcoded in the mutator itself, and be available as choices when the server is configured, and clearly visible. That way, the teams can agree on what setup they want, and go ahead with it, sort of like any other mod/settings we use (broadcast, zp etc). If that is too hard, then just go with one profile I guess, hence make it non configurable, but just make sure that it addresses the current issues.
