Guild Wars 2

I would like to know all the specs of critical strike procs working together, so for instance on my thief i have one Superior Sigil of Rage on each of my daggers along with trait skill Critical Haste. The Superior Sigils have a 10% chance on critical strike to gain swiftness for 3s (45s cooldown) where the trait skill Critical Haste has a 10% chance on critical strike to gain swiftness for 2s (30s cooldown). Now what i would like to know is when it comes to the daggers does the off hand dagger only proc when you are using a skill that uses the off hand weapon along with main hand only procing off skills that use the main hand weapon? I would also like to know how they would all proc or if they even all do. Like for instance if I proc Critical Haste then within the 30s could one or both of the daggers also proc? Then last of all if you had two or more of them proc off the same critical strike would they just stack timers or would the higher time override the others? Thank you

I have found out that your sigils will proc no matter what spell you use and that quickness does stack if you get more than one proc at a time.
