Guild Wars 2

According to the wiki this trait should give 10 second fury and swiftness boons.

When I use magnetic aura I get 16 second durations, which is 10 seconds + 60% boon duration from traits/sigils.

When I use any other aura I only get an 8 second duration.

The question is, is zephyr’s boon supposed to scale with +boon duration?

Furthermore if I apply a +20% fury duration sigil set; the magnetic aura applied boon becomes an 18 second duration while the other ones go up to about 9 (still not a full 10 second duration I believe).

I play a boon heavy spec and I’ve noticed lots of inconsistencies with which boons scale with +boon. However, this particular inconsistency results in 50% shorter duration and I find it to be particularly noteworthy.

I have also noticed there is inconsistency between the auras. If you apply shocking aura you get the 10 second default duration without any boon modifications being applied however if you apply flame aura or frost aura you only get 5 seconds of both Fury and Swiftness.

Could someone from Arenanet confirm if this is working as designed and that shocking aura is supposed to have twice the duration of both Flame and frost auras? It would help if the tool-tip contained more information as it is quite vague for this trait.
