3k sounds insanely low to me. Even if all 3k are on at once, let’s say for arguments sake ~1500 per faction, and let’s even be generous and assume all guilds will be small to medium size (50 or 100), which is not likely considering there are inevitably going to be several massive guilds. So take an estimate of 75 people average per guild - you’re looking at only 20 guilds per faction per server. But in reality less than that given how big some guilds get.
That seems super low. I love the idea of having a real community again where I actually know people, but that I would consider low pop. I want enough people on the server so that we have enough people to play with and against. Especially now that we’re all older and will have different playing schedules.
