How did people even play without the forum in the first place?
There was the discussion list before the forum.
Also, the fact that one can play without the forum does not in any way change the amount of frustration that results from losing a forum that has become established.
Also, if you really want a forum that badly, why don't you make one yourself to discuss things you want to discuss. Tom won't be able to stop you in your own forum :p
Sure, and if you want a given feature, you're welcome to make your own BattleMaster clone that has it in. Good luck getting enough people to make it worthwhile, though.
