If Duggan avoids the romance and writes them as teammates/friends, I will cry tears of joy. Gambit being an Avenger has been something I've wanted to see for a while now (also something I wanted to do once I started writing comics). My friends and I would make lists about who should be Avengers and Gambit was always at the top.
Also, think about it. This team already has Quicksilver, Steve Rogers, Spider-Man, Rogue, and Human Torch. Them's some big names. Haven't we all wanted Gambit to be more involved and start interacting with some bigger names for a while now?
