I think you should open beta registration and turn it on for ppl pking while no quests and wars in main server, since the main server is dead and most players are bored or tired of waiting gms answers on tickets.
It's ok for us if you keep playing Dota and have some fun for yourself, but I think we also deserve it, and the beta server is the easiest way for it.
Anyways, I'm pretty sure that someone will come here and say it's fine now (they like to play alone for some reason), but you, GMSP, know it's not.
Looking forward for the news!
