So, not 100% my idea... but I have an idea for the next set (or whatever the next set that the devs can work on and get released) of armor skins.
Shoulder Pet Armor skins!
Armor skins that have pets on their shoulders! Like, a Pseudodragon, or a cat, or a frog, or:
Maybe, just maybe, a pet only armor skin (as in, just attach the pet to already worn armor).
I dunno. I love the idea.
And to the naysayers out there about cosmetics: Remember, Turbine can make money selling cosmetics, or gamebreaking raid timers/mana pots/etc. You decide.
