Guild Wars 2

I am specced into Illusionary Inspiration and am attempting to maintain 100% quickness up time.

It doesn’t appear that SOI procs every time I cast Echo of memory and I am not sure what I am missing.

Is there an internal cooldown on the SOI proc?

Is there a global cooldown between SOI utility skill and the Echo of Memory phantasm SOI proc?

Does the number of phantasms prevent SOI proccing?

For example, when I do:

Tides of Time
EOM (correctly proc)
Signet of Ether
EOM (doesn’t proc)

Illusionary Inspiration has an icd. 30s untraited.

The utility and the trait don’t share cd.

The trait has a cool down equal to the signet but not a shared cool down. I use the signet CD to keep track of when I.I. should be up.
