Those purple, orange, and cyan gear tickets to exchange for one gear piece of your choice were awesome! Bring back more of those. So far, to my knowledge, they've only been available in one contest and during one special sign-in event. They should be a regular win in contests, if you ask me. They're far better than those silly purple or orange chests with 15 gear scraps I already have thousands of.
It also would be nice if you could trade them for gear needed in recipes. I have all Orange 1 or higher toons, so I don't need any purple gear unless a new toon is released, but a ton of toons need purple gear in their grinding recipes.
