Health of Multiplayer Community?

[novembr]

I am thinking about purchasing Assault Squad over the holiday (if they discount it) and I was curious about how healthy the multiplayer community is for this game right now. I am very disappointed that a game like this doesn't come with a map editor and instead charges for underwhelming map packs, but if the community is fairly active I can overlook it. So how is it?

*Edit: Seems I was wrong about an editor--I've learned the game does have one. Are customs maps used often in multiplayer games? What is the benefit of purchasing the official 1C maps instead of custom maps?
