The Primal Ritual Shell trinket is a really great trinket. It lets you choose between 4 buffs - air, fire, water, and earth. You can only do this at a specific spot in the Waking Shores. Air gives a proc increasing mastery, earth a proc giving you a big absorb shield, fire a proc to deal extra fire damage, and water a proc to heal yourself or an ally when healing.
The problem arises when you want to swap specs. The trinket does not allow you to have different buffs chosen for different specs. Any time you want to change specs you have to fly to the little spot on the map to change buffs.
Blizzard has done a lot of late to make it really quick and painless to swap between specs on the fly. It seems really counter to that theory of design they have embraced to required you to fly to an out of the way spot on the map any time you want to change specs if you use this trinket.
Please consider either letting you summon the turtles anywhere to change buffs or letting you set the buff for each spec.
