I knew you'd end up there
It is a shame that some people bought this game with a predetermined view of what an MMO is and how one should work - that was never this game, it is not WOW or GW or EVE with massive social hubs and so on.
You get 32 people per instance, even in the 1000 to 600 example we were using - there are some you'd never see even all of you were in open, as it's you and 31 others. This is why I'd not have used the MMO tag when advertising it, but hey, that ship has sailed.
Plus, as I've recently found out, you can play in open and just use the client to block connections to other people anyway - effectively playing solo, in open mode, so you're never going to stop someone who does not want to be stopped. Plus I read there are things to do with networking and routers... lots of ways to prevent interactions between specific players should 1 person get bored with another - yet remain in open play.
This is a solo sandbox, it always has been. It just had some half hearted last minute multiplayer bits thrown at it for whatever reason. For me, the reason I bought it was to multiplay with friends - so it just manages to scrape by on that front as we can do gaming event together, this whole persistent player faction warfare is never going to be what a lot of people seemed to assume it to be - it's not EVE, it's not Battlefield - it's not the stereotypical MMO.
Faction wars in this are people hauling goods, people doing job board missions not people doing PvP fights. The war zones are ok, buy they are a case of how many war zone vouchers are handed in over a 24 hour time frame, stopping 1 person handing in 5 when for the same time you could hand in 6... it just wasted time for the both of you and you'd still win.
