Just got in and started testing. After a bit of an adjustment period I'm absolutely loving the new Enh. The new animations and sounds give it great "oomph", Stormstrike particularly feels extremely satisfying to cast. Lava Lash still underwhelming, but in the right spot for its feel as Maelstrom dump in gaps.
I've only spent an hour on testing the talent setups so far, but it feels like we have several quite different possibilities that feel satisfyingly different in rotation style. A few I'm a bit "eh" on, like Ascendance now - it's already hard to dump Maelstrom without capping with Wolves and Doom Wind, Ascendance seems to waste even more - might be a viable option with Lightning Bolt as 2nd main dump, which feels hardhitting but allows for almost no Lava Lash in 680 gear at 100.
Generally very optimistic, I like where this is heading. It feels like the spec finally has a focused orientation and flavour, some kinks to work out but I'm loving it.
