First i sorry for my poor english, but i got 3 good ideas, and maybe T17 can change that things:

1.When host-player quit, other players can play and end game.

2.Can ban selected players,penalty system for quitters. Quitters can't join on our host again when we banned that f@#!er.

3.Simultaneously at ordering/selecting worms to positions (When that option select) in online game, you selecting your worms positions and your opponents in same time, but you don't see where opponent's selecting their worms. Is too better than long selecting by turns.

What T17 can do it? What you think about that?

First of all, T17 has stopped maintaining W:A for more than a decade; the current maintainers are Deadcode and CyberShadow, and they do that as an unpaid hobby.

1. Technically impossible for now, but in the major W:A 4.0 update having several hosts for the same game is planned.
2. Banning isn't planned as far as I remember, however the reputation system (with penalties for quitters) is also planned for W:A 4.0.
3. Sounds like a nice idea, but it sounds like a 4.0 idea to me too.
