Maybe it is impossible or Team17 woudln't agree with this idea, but, if company (with Cybershadow) will agree (or it is able to do it in rewritten engine), it'll be fun to play with player, that have team of worms with not the same weapon select, different health, etc.
And I'll guess nobody will agree with this idea, especially Cybershadow with Team17, due to Worms "standards"

*I mean worm options (health, treat time after using or dropping weapon, how long can you move your worms, availability to move your worms, ammo stocking, positioning)

sometimes it happens that you must teleport manually, when map is too big and too many worms. xd

maybe for rope races where you have 10 seconds left and come to a huge 20 seconds climb, you skip a turn so those 10 seconds are not lost

From interview with T17 about WMD as e-sports:
"Maybe we would explore that and maybe we take a leaf out of Team Fortress’ book and have the map symmetrical so everyone gets a fair advantages."
Therefore this suggestion to WA: ability to mirror (one side of a) random map, as to make a map that is identical on both sides.

Could be nice for schemes like elite.. or just to have an easy way of creating a fort-like map out of maps that aren't designed to be.

You should add the ability to upload Maps Mods and Addons to the Steam Workshop
Also it would be great to see Achievements and Steam Trading Cards
(If a game has Trading Cards there is more chance people will buy it)

In WMD the global lobby chat is also accessible in the game lobby. Would be nice to have this in WA as well, so that you can call out a buddy who's left behind in #AnythingGoes without needing to exit the game lobby or switch to snooper. And also to advertise open spaces when nobody joins up.

This could be done using external servers and by selecting a player (with F1,F2 etc.) and then pressing down a button while talking (next time you press the button you will talk to the same person that you have selected)

Let someone reconnect from a network drop and let the hoster decide to pause the game and wait for the person, or continue without the person who dropped out.

Introduce a New weapon called "Super Fart". which fires in the opposite direction.
So if enemy worm is in front, worm should face opposite direction to use Super Fart weapons.
worm should do a jiggle and giggle before Fart sound and it should hit like a baseball Bat.

If all the features of rubber would be build-in with W:A - no /telv no desyncs...

Seeing default blue water 24/7 is quite boring. How about an option to keep acid mode enabled without a need of typing /h2so4 each time I start W:A?

allow to view the whole chat history in a game since it started, by pressing ctrl+page down. so that it scrolls up to the very first message posted in a game.

My first game was Worms Reloaded before I found this gem, but in Reloaded the weapon drops would include invisibility amongst other things, and invisibility only seems to be available by adding it to every worms inventory.

I was wondering if new update has new test stuffs like "Bungee Shopper stuff" (i.e. /bs), in which everything would be same like /ts except worm won't be hanging after turn end, and "Darts stuff" (i.e. /ds), which would be useful to not get messed up by accidentally drilling all worms, whch means worms won't hit each other at all.
These teststuffs would be pretty useful to get the scheme activity back.

I'll try to translate everything (which was in version 3.7.0.0) into Polish. Would it be possible to be able to add these characters: ą, ć, ę, ł, ń, ś, ż, ź?
If anything languages will be added to the new version I would try to translate it.
