Just posting my feedback here as I am not in the alpha.
IMO as a previous shaman main and with enhancment being my main alt in bfa they are in a good spot (in pve). However I am not against the fundamental changes being made in shadowlands.
This is huge- Maelstrom weapon NEEDS to have its stacks increase the healing and damage of the next spell by 20% per stack again. That was a fundamental part of that passive before Legion and it needs to exist for this rollback to not be a straight nerf. Honestly they could just keep the Legion and BFA iteration and add chain lightning and this would be a better spec.
Searing Assault- This should spawn the totem and cast flame shock on your primary totem, it should not have 2 interactions with abilities you have to use before it. Otherwise it will feel clunky.
Spirit Wolves- these are a joke without the talent. Buff them or make ascendance baseline again.
Lightning shield- I prefer the BFA version as it has a cooler interaction building up to the lightning damage as otherwise since we are not tanks it is useless. I would say keep the BFA version or people are just going to use earth shield since lightning shield is useless when not getting attacked.
Survivability- This is an era where dhs can full heal just doing their dps rotation and have a 1 minute cooldown defensive, enhancement needs something more than astral shift and capacitator toem while good in pve is a joke in pvp. IDK what it could be, earth shield is not strong enough especially now that you can not have it active with lightning shield. But they need more mitigation, preferably passive.
WIndfury- this proc is a joke, far from its classic days where now it does no damage without Forceful winds talent. Buff it or make forceful winds baseline so it feels useful.
Weapon Enhancements- I am fine they are making a return but remove this silly thing forcing you to have flamebrand on your offhand to use lava lash.
