If you could pick one feature from the new titles and put it into WA..

[HHC]

Let's see 

From the top of my head, special features of Reloaded, clan wars, revolution... WMD..
All can vote for 2 things.

[Peja]

water + classes > crafting + vehicles

[HHC]

I voted new weaps (there's so many!) + water.
All are nice additions in their own way, but these for me offer the most opportunities for interesting new schemes making

Buildings, crafting system (fixed version of it), new terrain textures / graphics, ranked online mode and built-in RR mode. Ops, that's 5 Haven't played other newer titles besides WMD.

" Build-in RR mode (automatic placement, finish 'gate') "

Does this exist in WMD? First I heard about that

[HHC]

its from all new-gen games (read title)

Ah right. Which game has that?

[HHC]

Reloaded had it, not sure about CW and Revolution.

Hedgewars allows to have per-hog hats, something that none of the Worms titles have

[TheWalrus]

Voted for hats and only hats, all bow down to the power of hats.  #BRINGHATSTOWA

[philie]

well, most of the stuff can be done with px.. (or is already available with px)

[Sensei]

Crafting crates would be good stuff for some new WA schemes.
Would require great amount of strategy when to dismantle/upgrade and on which weapon should it be done.

Playin WMD lately. Still feels weird and slow, but have fair amount of great moments. Soundbanks and ingame music are off the charts.

I can't pick just two. I've played all of the Worms games, and currently play WMD a bit. Features that I love from games post-W:A are:

-sentry guns (the ones in WMD are the best!)
-hats
-dynamic water (adds a lovely layer of complexity / strategy to the game)
-worm classes (a lot of people don't like classes, but I think they are pretty great in Clan Wars. The heavy worm could be nerfed a bit, but aside from that, they are well-balanced and it just adds to the depth of typical Worms gameplay)
-physics objects (and girders that are 'solid' rather than treated like a part of the terrain)
-buildings (one of the new things I like about WMD)
-crafting / coin crates (I think that crafting COULD be good in WMD if it were rebalanced / fixed; right now it's a mess)
-so many awesome weapons and utilities in the newer games I don't even know where to begin
-very in-depth personal stat tracking from Clan Wars / Battlegrounds


I personally hated the 2.5D games at first, but grew to really enjoy them, especially Clan Wars. I think that CW is second only to W:A. WMD is a huge disappointment so far. it looks and sounds beautiful and it has loads of potential, but it's up to Team17 to listen to the community and fix things. For now, I barely even wanna play it.

[skunk3]

I just wish Team17 had sense enough to recognize that all they need to do is keep what is great from their past games and just continue to build on what is good and liked rather than trying to reinvent the wheel every time they make a Worms game. If they would fix WMD and somehow make it able to support dynamic water, it'd be insanely good.
