Guild Wars 2

I bought 6 Superior Rune of speed, Putted them all into my armors. It (rune of speed) says total 25% movement speed increases when I put 6 of them to my armor. But my character was obviously slower than who used movement signet(which increases movement speed 25% too).

This has been posted and noted by the devs (but still no fix): https://forum-en.gw2archive.eu/forum/support/bugs/Runes-of-Speed-not-giving-6-piece-bonus/first#post2835686
