The trees itself are fine, elemental didn't get much buffed imo since i almost all pick the same talents again as i did last time, thx to combining a few i can parts of the new talents.
In resto tree i pick all the same talents besides 2 points which i can spend in some dumb -manacost talent.
What elemental/enhancement shamans want is a reason to go elemental/enhancement in endgame raiding and not manatidespec, and even if u guild allows u go to another spec they want u to heal/have all ur healgear on and heal at all times/at bosses/when there aren't enough healers.
Where druids (Aspect of the pack/The moonkin) and priests (shadowdamage debuff) can go full dps and help out the raid elemental/enhancement do not have such a talent, and now mages
Get another debuff to the target.
If shamans would be able to the same this would greatly open our options in endgame raiding besides being healbots regardless of how far ur allowed to go by ur guild.
This doesn't have to be a debuff directly, it can also be a talent which gives 1-5% mana/health back to the party whenever a spells/melee move crits for example.
