-Mobility has fallen behind. Rets and Dks had some of the worst mobility until TWW made that a lot better. Enhance sham is now the least mobile melee in the game in pvp and it shows. Improving Feral Lunge baseline would be great and largely all thats needed, ie a baseline talent learned at a later level “Improved Feral Lunge: Feral Lunge cooldown reduced by 15 seconds and now grants immunity to roots and slows for 2 seconds when you land on your target” would be great.
-Honor talents are congested with defensive talents and losing AG hurt our personal survivability. Grounding, Stormweaver and Burrow are all very good defensive talents, with Burrow and Grounding being practically necessary leaving us with 1 actual choice. It would be nice to get Stormweaver in the spec tree for Enhance or possibly Burrow baseline. Something to free up an honor talent slot here. With the loss of AG, it’d be nice to have an extra defensive talent that isn’t in honor talents that we can take. Another option is the removal of burrow completely with the addition of a 2nd charge of wall. It is also possible to update current defensives in the class tree, ie “Earth elemental grants you an absorb shield when summoned” or "Earth shield grants the Shaman 5% physical damage reduction (can be different % for ele/resto), things like this would help without adding new talents.
Enhance is really fun in 11.1, but has some issues especially with uptime and having too many defensive choices locked behind honor talents. Loss of AG hurt the spec pretty hard survivability wise as well. We only need a change to one of these things. We do not need improved survivability -and- improved mobility, but we do need one of those weaknesses to be improved. My choice would be mobility as that is just more fun and enjoyable without effecting the game as a whole like more defensiveness would.
