As it is right now we've got armor lines that resemble the Chromalisks, Wolvers, and the Jellies, and we have the ability to use a Gremlin weapon. I think we need more because these are awesome.
Here's some equipment I'd personally like to see:
1. Armor/Costumes resembling the armor Gremlins wear.
2. a Lumber Armor/costume (This talk of Bark Modules makes me think we might see these soon-ish. Also maybe a giant log club weapon)
3. Gun Puppy Armor/Costume (Possibly accompanied with a special gun that looks like an X-buster or some other kind of arm-mounted cannon that has a Gun Puppy head built onto it that has little to no crafting potential- because yo dawg, Xzibit heard you like Gun Puppies so he made you into a Gun Puppy wielding a Gun Puppy, so you can shoot like a Gun Puppy while looking like a Gun Puppy)
4. Trojan armor/costume (those guys are badass, seriously. Also I want to be a HOERS)
5. Devilite-themed armor/costume (Like a business suit, duh).
and a kitty costume :P
