New confounding suggestion with runes/sigil?

Just curious if anyone tested whether the trait stacks with sigil of savagery/runes of mesmer, I seem to remember old bug where they don't stackBut yeah if it does it'll basically turn any 1s daze (diversion, MoD) into 1.75-2s, pistol 5 to 3s stun/4s daze, 0.5s daze from sword ambushKind of like the old annoying DH trap build back when it was still viableIt won't lock down people for sure, but it'll give decent breathing ground against opponent with 1-2 stun breaks only

I'm curious as well but I don't think it will stack.These kind of traits have never stacked and I don't believe coding for daze/stun durations has changed as they just altered the value.
