Guild Wars 2

I recently just got my Mesmer to level 20 and decided to starting testing around with her Adept Traits, when I noticed some of them don’t work.
For example, within the Dueling line, there is a trait called “Desperate Decoy”. It’s suppose to activate when the Mesmer gets down to 25% health, but it didn’t. I didn’t have no other illusions/phantoms out.
There’s also a trait within the Chaos line called “Metaphysical Rejuvenation”. It’s suppose to activate at 75% health (with a 30 secs cool down) but it doesn’t seem to be working either.

Is it bugged or are there other unlisted requirements for those to become active?

There are many broken traits for all classes, but afaik the ones you mentioned should be working.

Desperate Decoy is a well-known bug.

One theory holds it activates at 10%…considering a hit for 11% kills you outright you’d better be pretty tanky.

The other theory holds it activates at 25% but is somehow subject to a hidden internal activation timer, or in other words, bugged the way Signet of Illusions is and therefore borderline useless.
