Guild Wars 2

Im just curious i have travelers runethat grants 5% movement plus i use signet of the hunt. I get 15% passive movement bonus, however when i use call of the wild i seem to be traveling the same speed as anyone with a swiftness boon. Shouldnt i have 48% movement bonus when i have swiftness?

I believe movement speed buffs do not stack, instead it just takes the highest or largest buff and uses that.

I just read it at the wiki. That should probably be stated on the skills or bonus that it does not stack.. not sure if it is there and i just missed it, but if its not it should be stated.
