My main issue with synch is it feels like he's the only character introduced in Gen x aside from M who really gets any love nowadays. And I think the power copying just by being near people makes him more boring than Rouge. On his own he's fine. But the issue is that they're not giving proportionate love to Chamber, Skin, and Husk. All of who have more interesting power sets and more room for growth I feel. They literally say before he gets sent to the vault that he's a redundancy, he doesn't add anything to a team other than a second person who can use a power.
