Druid Form "Shapes" Uniqueness
As of now each and every spec can change to all of the forms (except Moonkins)
Since in the lore each and every druid has only 1 form and he/she belongs to only one Druid Faction "Druid of the Claw, Balance Druids, Ecc"
Note also this: since Lore also states that Shapeshifting is kinda time consuming and hard to do, this will give more Immerison for each and every druid spec.
To make Druid become more Unic to there specific speak and Class Lore you should make it so that if you as a "Balance druid" should just have Moonkin form (Spec Spesific from) and Travel from.
This would Balance the druids out and give each and every spec more Uniqueness.
PS: since In Legion you can change beetween each spec, it would Reasonable to have this implemented, since if you have played with Moonkin form and are tiered about the Huge Chicken form " :P ", then you can just change spec and go all Cat form.
PSS: Since you, Blizzard are focusing on Pruning and giving each class more spesific and better buttons to push for players, then this would make a WONDERFUL change to the "infinite number of Druid buttons..."
PSSS: Since Bear and Cat Spec are Separat they should also be Unique, so if you choose the tanky way, then you should just have Bear form. if you want Cat from, then you can just Respec, simple and easy.
What do you guys think? lets do some brain storming
