Meta will most likely remain AST/SCH unless the stat squish makes SCH an absolute slog of a class that can't keep up in heals, in which case SGE might take the spot.

WHM is currently looking to be in the worst spot it's been in since HW since it's MP economy is now more on par with the other Healers so it can't simply power thru with infinite MP like before so now it has to rely more on the Lily System, resulting in even less DPS from the healer that's whole utility is its damage. Either buff Misery, leave Thin Air alone, or give them some actual raid utility so they aren't a joke because it wasn't funny in HW and the joke has gone on for long enough.
