Maybe this has been suggested, or thought of or whatever but I didn't see it.
OK, I'm not going to be someone who will complain if presets aren't free as I haven't figured out how to make them yet anyway, buuuttt I figured I could suggest something.
ANYWAY, what if instead of hosting the presets on the server, they could be added into the Presets folder on the installer, and then when the game is patched the presets are put into everyone's games?
Maybe that is the same as being hosted on the server, I don't know much about that kind of thing myself.
But if the game has those two default presets, couldn't the game come with everyone's presets?
Providing people set up everything before sending it to Raz/Kovu/Whoever would be in charge of that, as it might be a lot of work putting that in there. (Again, I don't know how to make presets but recall reading about some words that needed changing to the players name? Not sure)
I don't know if this is hard or not, or if it is what hosting it on the server means, but I figured I would suggest it anyway.
