Worlds is going to happen soon and settle everything once and for all.... Or at least for a few months
I give Rebels an 86% chance to win worlds.
Bomber K-wings, Ghost, ARC-170, and Biggs of course.
There's a high chance Rey with Finn & Kanan crew will be viable.
X7 Defenders counter U-boats. This simply balances the meta.
B-wings and X-wings are still not relevant.
For Scum: Starvipers, Scyks, Kihraxz, and G1A are still not relevant
The G1-A with 1 AGI was DOA in an ordnance heavy Meta. Which is a total shame.
