It's pretty strange this kind of server isn't working for cRPG yet. Currently, all Team Deathmatchers are playing on Rageball server, which is just silly.
We have so many battle servers, including new EU_9 Battle server with 249 slots, which stays empty all the time.
I have nothing to battle servers, but do you really think new players will chose battle game mode to learn to play? Few seconds in game, then wait few minutes for respawn, how can you learn anything this way?
I know there is also siege, but siege is something not everyone likes. Attackers side always trying to go up the walls, die on the ladder, respawn and repeat that all over again, while defending side archers camp the towers, infantry stays at key points in castle with great mauls ready to strike. Siege is just so predictable and boring after some time.
Team Deathmatch would be also perfect server for testing. If you want to test weapons, armors, horses it's the best mode to quickly check how do you like specific items.
And if you have few minutes of free time, you can always go TDM and enjoy a while there. It's something you can't really do on siege and especially battle server.
So why not change EU_9 empty Battle server to Team Deathmatch mode for a while? It can be on x1, I don't think that would be a big problem for people who just want to relax there.
BTW: I don't really like TDM game mode (always prefered Conquest over it), but even I would visit TDM server from time to time. It's always something different, and it's already implemented in game. So why not at least try it?
