I personally don't like using EvE, not my game, tried it many years ago and found it not my thing at all. I've been in units for all kinds of games online, MMOs and not, sometimes they catered to the units, sometimes not, didn't matter, the units formed regardless.
Some gave us housing/bases, ways to buy stuff cheaper in our guild house, crafting cheaper in our guild house, etc. All fun, all great, and none of those had any sort of BGS or any way for the guild toys to actually influence the game itself, they existed, that's it.
People want bases in Elite, even David wanted to, in 2014 at EGX, see players have a station they can call their own. However, due to the BGS and how everything is interlinked, giving us control over those stations becomes a problem. Units would want to control their station, that's rather the point of owning them after all. Access lists, setting prices on commodities, prices for repairs, reloads, what ships can be bought and the prices for them, people will want to control that, they'll constantly whine about not being able to if they can't, and we'll see the same arguments..'there's not enough for my unit to do, we're quitting unless you fix that, X amount already left over this'. That's a given, it'll happen, that's essentially the gist of the OP's reason WHY this needs to be done! People are leaving because the single player game they bought doesn't support large teams, so give them what they want or MORE will leave!
Me, I knew what I was getting with Elite Dangerous, I haven't tried to get my fellow Rats to come here from our other games as teammates, because what we like to do as a unit, it's not supported by the game, the GAME isn't designed for teams, simple as that. I was aware of this before I bought the game, I'm good with it. I am one of those people who looks at a game before I buy it, I make sure it's something I'll like and how it plays, does it support anything beyond single player being a huge thing for me. Outside of the Witcher games, Elite is the first game I've bought in a very long time that isn't team oriented PvP combat based. It's simply NOT that type of game, no matter how some people keep insisting it should support teams and PvP and this and that and the other thing they want from their favorite game.
Fair enough. I think there is a severe lack of understanding when you apply the term base with elite dangerous, and what some of us might be asking for. Stations are a no. I personally have no interest in running a station, infact I think that a player group running a station is pointless. I just see a lot of people attaching any aspect of a multiplayer feature that has been in many other games, to the eve label and the worst common denominator then shoehorning that onto the OPs request or any post that suggests multiplayer feature x. It's really bad honestly. Instead of saying "Well this wouldn't work because of reason x" Lets take a step back and look at what the OP is asking, or what many users in this forum are asking. "Some form of player group content, or co-operative play in a more urgent setting" Alright so how would that work? how would player controlled bases/housing or guild outposts work in elite dangerous, What would work for elite dangerous and the larger player groups that want to do their thing?
Forget about PVP for just the moment, what about explorers, or your fuel rats that you keep bringing up? How about having a small outpost to base out of, re-supply and repair when operating far outside of the bubble? Simple things like that. Elite right now, is as you say not a team oriented game. However it is not written in stone that more systems in place won't be added to facilitate that particular nature of the game. No one here is suggesting that all aspects of solo play should be removed, solo players have no reason to jump on us asking for some more co-operative content. It does not affect them.
