The thing is if you realese server files which are (or might be) unstable, everyone would demand quick fixes and updates for them aswell. And the tolerance for unstable servers wouldn't be as high as you guys might think. You guys are reading the forums, the most casual players don't.
Also TW wouldn't have access to any server logs and during the development they want to gather as much informations about crashes etc. as they can get.
And they would get 'even less' than right now.
"We could send logs and crash reports to taleworlds"
Yeah.. I bet :^) Everyone will do that for sure!
"They can just autoupload our server logs"
Sure thing, more traffic, every serverhoster would love to see this. Aside of that you would be in trouble with the law depending on the player region / server region.
As much I would like to host my own server, I think it might hurt the general development right now.
The argument "But we would have more players in general" is invalid in this case. Those players would still not play on official server nor use the matchmaking system.
It's just not worth it as long as they cannot provide stable server files.
Edit:
You would btw. require working gamemodes to host: Siege, TDM, DM and at least Skirmish as gamemodes.
But afaik Siege still crashes sometimes and Skirmish doesn't support teamdamage nor players spectating (but this might work in meanwhile, I don't know)
