We used to have one, it was always empty. Maybe that's the reason there isn't one in entire UK :/
It was only empty due to too many cheaters and people losing XP due to dynamic IP
And then no one listened to me. You can save xp on your nick. The only trouble is you can copy xp from someone else. And for that shall be given permban.
I used to play war3mod with savexp. 2yrs on daily basis in the biggest Latvian server.
And war3 was full 24/7. But superhero. No doubt why it was empty. Superhero is booring and to difficult to the new starters comparing with war3.
If someone will give a try, go for war3, not superhero (superghetto)
