I used the 2 free playtime days blizz gave last weekend to check out these talents.
Some classes got shafted (especially druid) while others got better.
However overall there is no innovation, no new things to try, "cookie cutter" builds are gonna be mathed out.
If you played Shadowlands then most classes will play the same in DFlight, which is a huge disappointment for players who dislike SL shallow classes.
