I feel that it is important that the community servers are addressed. Not giving flexibility for a community will lead to permanent player loss in the long run. I am aware that the early access focus is on the single player element of the game, but given the amount of players that played Warband over the years that had stopped playing and are now returning to the competitive fold or to the communities that hosted events, it is imperative to nurture them, for the game's own survival for the future. If we start bleeding players now, it will spiral out of control. If you look at other games like Fallout and Anthem (while not saying that this game will end up like them as they were handled horrendously), they have bled players to the point where no future patch can bring back a bulk of lost people. Lost people leads to less revenue in the long run for the company (for future products/DLC) as well as less players around, leading to a faster decline to the current player base as they will feel like the game is dying. At the stage, just having dedicated servers will be enough for clans to handle their own game modes, for example doing a TDM server but the clans play it as a battle with 1 Life each player until one side gets wiped then they reset and meet on their sides of the maps again and they go again, until Battle game mode is introduced hopefully.
We can wait for a delayed feature for singleplayer, its already a solid experience as it is. I don't think that the priority right now is to add new features for singleplayer. What would happen is, new feature gets added, we go to check it out, "oh cool look at X feature its awesome", I use it a few times, then the adrenaline is over, back to square one, communities are still not playing with each other or against each other. Communities cannot wait for a prolonged period without servers. While the hype and the excitement is high, its important for communities to have their own custom environments so that even newer players who never played Warband before, can look at the game and understand that there is also a competitive aspect that carried over from its predecessor, rather than just "another quick match, flavour of the month game", whereupon they then move on to the next "flavour of the month" game, some battle royale etc. The community is what will retain the players, not singular additions of single player features.
