All classes feel... viable now?

Played a ton of WT the past 2 days and honestly I've seen much more variety than I have all S4. Lights melting with 93r's, Heavy's using their new weapons, and Medium now feels like a support role and less like a jack of all trades.

It's early in the season, and I know metas will happen no matter what. But it feels good seeing so much class variety now.
