Guild Wars 2

I don’t know if this is a known bug but the #6 bonus on this rune doesn’t scale with
“Sleight of Hand” nor does it scale with “Tactical Strike”, so the rune is pointless to have.. I kinda liked the thought of prolonging Daze.. but it doesn’t scale at all.

Is this rune broken with any class or just Thief?

Nvm, my math skills aren’t very sharp today, what is happening is 33% daze duration, from a 1s base, is 1.3s.. gw2 only scales to 1.5, so 1s stays 1s, even though it’s supposed to be 1.3s, so basically, the rune is useless.

This is incorrect. See my testing of daze duration with all sources capable of doing so:

Runes of the mesmer correctly extend duration to approximately 1.3s. The game does not, in my experience, round like that for daze duration.
