As a druid, I keep gear sets for 4 specs. I have 3 for my main spec (raid single target, raid aoe, M+) and that puts me almost at the limit, maintaining 3 total sets for guardian isn’t possible currently. Additionally, with corruption and horrific visions and pvp and multiple options for major essences, I’d like to have even more slots for gear sets. I realize this increases complexity and may not be a reasonable thing to do but doesn’t hurt to ask, right? 
I’m willing to pay a little more for it, if that makes a difference.
