If you could add one thing to WoW...

[Christonya]

What if I could remove some things..?

Given that you're asking for an addition, and given that blizzard has decided to turn the game into a diablo mmo, solo greater rifts. Like M+ Except solo, so when your friends arnt online, you can still progress / do some thing.

[Polarthief]

Devs who actually play every spec and don't just throw darts at a dartboard.

[Nayami]

+1 Armor dye

[Daymanmb]

Being able to /rude and /spit other players again.

Thats a thing?! Legion removed it?

player housing/guild housing (I like the ships idea , Assassins Creed:black flag style with pve/pvp components if not ships then I'd go for a stronghold sort of system like they will have in crowfall.. destructable worlds with seasons (on a 1-2 month rotation) sound epic too)
-you should be able to hearthstone other players like you can duel/pet battle them.
-tinker class (long time gnome player so any reason to give gnomes a storyline is a welcome one to me)

-jumping puzzles / raidfight that consists of nothing but jumping/obstacle course... super mario style... should have a green pipe at the end.

[Kellorion]

More non-queable content.

I had suggested once that the garrison and now order hall mission system could have been implemented instead as a boss-encounter in an interactive format just like pet battles.
So instead of something you simply wait hours for, it is something you spend maybe a few minutes actually doing yourself.

I have not really thought about it being interactive, since i think it would be hard to make a system, where you control 10+ characters at once, but i like the idea If you look at the very first version of the Garrison showed at the blizzcon before WoD, there was alot more to do in it with all the followers You could fully gear them out, you could send 5+ characters into a raid mission, which gained old raiding transmog gear and special cosmetic items. I would love to see such a system be implemented when Legion is over: A game within a game. It could be fully optinal to do, gave no power or money reward, but just rewarded you with cosmetic stuff the more you did with it. You could maybe even have a mini garrison, where you could see all your personal npc raiders

[Eleccybubb]

I can't think of just 1 so I'll pick something from a few MMOs.

FF14. Dyes.
Rift. Housing.
Guild Wars 2. Masteries.

Some high difficulty solo content. It's pretty much non existent. I'd love a solo scenario that used keystone scaling. Give some AP each level you clear and a weekly bonus based on your best. Get some rewards and gives a good chance to hone your skills on your own.

that would either take forever to create a experience specific to each classes strengths and weaknesses or would be totally garbage for 80% of classes specifically those who cannot do leet deeps and self heal. terrible idea
