So for me personally, I love the changes they made and the way they play now. It feels very similar to how they played back in WOTLK or Cata, especially with the return of Maelstrom Weapon, being able to instant cast chain lightnings again feels awesome. And if you're going Venthyr, being able to insta cast Chain Harvest is going to be super OP in aoe situations. Overall I'm looking forward to seeing how it plays out with legendaries, soulbinds and raid/mythic + gear. Playing enhancement shaman on the pre-patch has been a blast for me so far
However, I can understand that for some people the spec might feel too clunky, especially if you're speccing into a bunch of active abilities and managing a bunch of GCD's. It's a lot of micro managing, and if you played enhance in WOTLK or Cata, it's not as bad as that but it's definitely similar in that regard. But imo it makes for a more interesting and involved rotation and I prefer that style of gameplay
