Example, in France, We asked that our LA got also Mod power to get a quicker reactivity if there is a problem on forums, but We dont have exclusive Mod.
In Slovenia, with ~600 teams we also don't have a Mod. I'm doing LA's and Mod's work, and then there's GM who is also doing Mod's work. So I'd set a dedicated Mod only in countries with 1.500+ teams or more because only there the forums are really active (Poland, Spain, Italy, USA and a few others). Those Mods would certainly earn their supporter, while in smaller countries dedicated Mod is not needed IMO.
