I don't think there is anything wrong with the current speed of the worlds. It's just new worlds and resets are sooo rare, that if you're not around at the beginning of the world, you have to wait a year unless you want to play when the top player already has 1 million points.
The only world that I can remember being stopped is Rise of Heroes. I led the #2 alliance in the world when they closed it, and we had just taken down Domination Complex and that noob oatparchasi (rimmed him lol. Ever hear them mentioning winning a world, see if they remember that. We tore their alliance apart). Yet, I wasn't too upset they closed the world, because I figured that just meant they would reset every world every few months from now on, which, while not ideal, at least there was some consistency with that.
But to have the world I played close down, and then a new world never made or an old world reset, I must admit that's a little annoying. I want to play this server... but I don't want to have to grow from 0 points to 500k, only to have there be guys 10x my size just because I joined way too late and there's no new worlds.
Edit: I'd also like to point out that these forums are completely dead besides ABAIN and Geode lol. That's not good. The devs are looking at these forums... yet no one is posting in them. If you increase your member count, you'll get a lot better results on the forum, with players providing more feedback on what they like and what they don't. A lot of people hate gold trading, but never got the chance to stop it, mostly because a lot of guys don't even know the beta testing server exists. What should be done, is you should ask Baudin Toolan on the en server, and possibly other community managers from around the world, to post in their forum there is a new world opening here. This server has never been advertised really.
Just saying.
Devs, I'd also like to enlist your help. I'm not sure if you guys really have any say on opening new worlds or not, but I know if you said to the people that do have a say that you would like to try and get these forums more active (which you really should), it would go a long ways.
