Swiftness/movement speed
max swiftness is stacked at 33%
u will always be slower if in combat
No they don’t stack. If you have multiple movement buffs, you just get the fastest buff available.
This is usually swiftness but I think mist form gives something like +50% movement speed and “One with Air” gets maximum out-of-combat movement speed (in combat) — it doesn’t actually double it, unless walking backwards I guess.
Wyrden is correct, max speed in the game is capped at 33%. So the effects of your traiting + sigil aren’t making any difference if you have the swiftness boon (and without the boon, they are just overlapping each other. Drop one or the other.) The swiftness boon’s duration stacks, but movement speed does not.
Also re: Mist Form, which gives +66% movement speed in the tooltip, does not actually make you move faster. What it does is counteract the effects of conditions like chill or cripple when you go into Mist Form, so that you move at normal out of combat walking speed.
One With Air’s effect of +100% movement speed similarly negates chill/cripple and gives you the normal out of combat +33% swiftness as well.
I have zero idea how any of this effects the speed of walking backwards.

Your post covers just about everything, but if you Mist Form while affected by chill or cripple, you’ll move at normal in-combat walking speed. If you were only crippled, you’ll move with a 13% buff to in-combat speed.
Traits like One with Air can bring you all the way up to the 33% cap on their own, even while you’re chilled – but this is why they don’t last very long.
