I've had the chance to play quite a bit of WMD by this point and here's what I think...
WMD sucks.
It has so much potential to be good, but for now it's shockingly bad. The claim of 'over 80' weapons is a joke, the crafting system sucks, vehicles suck except for the occasional funner, the ranked scheme has gotten better but still sucks, the ranking system itself is worthless (it is basically grind-based), you can barely find hosted games during what should be peak hours, there's loads of bugs, a glaring lack of content, the rope mechanics are better than recent titles but still not close to as good as W:A, the fkey mapping is all f@#!ed up, there's a major lack of customization, and perhaps the most annoying part of all is the community itself. In the newer Worms games, people won't think twice about choosing a particular player and singling them out, and attacking ONLY them until they are dead. People also gang up with others and will do the same thing... like unofficial teams. It happens all of the time. Say I am playing in a 6-player FFA match in WMD... what ends up happening the overwhelming majority of the time is this: After about 5 turns or so, everyone makes it their holy mission to kill me because it's obvious that I know what I'm doing. I've tried explaining that even in a no rules match, that's just bad Wormsmanship. That's not how we play in W:A, and it's just lame behavior. Newer players don't give a shit. They will be as cheap and ruthless as possible to exterminate a 'threat,' even if that means totally screwing themselves over in the process. It's maddening. If any of you decide to buy and play WMD, just EXPECT to get ganged up on / singled out, because it WILL happen.... and unfortunately, there's a major lack of defensive items / utilities in WMD, so you can't defend yourself very well. In Clan Wars there were classes that could be used strategically, as well as a much wider variety of defensive options, like lucky charms, teleshields, lightning strikes, etc. In WMD you basically get select worm, girder (no girder starter pack), and a crappy magnet.
Long story short: WMD looks great graphically and the rope isn't terrible... but it feels unfinished. It feels like it should still be in beta. Worst of all, the newer players are annoying as f@#!.
