For what it's worth, they're *slowly* making more room. Headstart was 6 NA, 4 (I think?) EU. Now they're at 8 NA, 7 EU. They've also expanded server capacity by 20%, then another 10%, then yet another 10%.
They're taking the opposite stance of, say, Warhammer Online. They'll both probably end up the same. Launch with too many, servers get too barren, your game "dies". Launch with too few, people get frustrated and move off, you lose business that way too.
And of course the problem just makes itself worse. It becomes an arms race of anti-AFK macros, sitting at character select, and people using remote tools to get in the queue early. The only immediate real solution is to get people off the popular servers. But even though the game has only been out a week, you'd be hard pressed to find people willing to start over. FFXIV locked servers for character creation. That helps queues a lot. But then that completely prevented people from being able to play together at all. I couldn't get on the server with the guild I was going to launch with, so some of us splintered off, and I never lasted past the initial month because of it.
GW2 was the only MMO where things weren't an issue. I never tried ESO, did their mega-server thing work out? However, ArcheAge is different, in that there's non-instanced housing. There's no solution that works for a game like this. Too many guilds picked the same servers.
