They've mentioned that upload speed can really hurt larger games as it pushes a lot of data; they're finding that quite a few people with broadband connections have really poor upload speeds which really hurts in a p2p connection system
This is a load, they blame everything but themselves. First it was European DSL providers, then when it affected the US too it was some crap about ISPs filtering JUST them, now its upload speeds and I'm sure next week it will be something else. Plenty of users on their forums have tried with fresh installs of Vista and XP, no antivirus software, directly connected to their modems and still persist in having major problems. They claimed it must be ISP filtering but one dude actually got access logs from his ISP to prove it wasn't.
Game itself is pretty rough too, lots of bugs and annoyances. No control groups for minions, you have to use their preset UI buttons and hotkeys for things. You can't even click on the minimap to pan the camera there, I mean seriously wtf.
They needed to do a big public beta test and they really need to shitcan the connection issues. They keep saying it's resolved or will be resolved soon but it never is, each patch breaks it for as many people as it fixes. This game will be barren in six months at this rate, it went from 15,000 active users at the sale point to 3500 in under a week.
