"The duration of conditions you apply lasts x% longer."

[Taylan.2187]

I spotted this wording on Rune of the Trapper while playing around with PvP builds. It sounds like it should do exactly the same thing as "+x% Condition Duration." (I'd check but it costs 5g.) Is there any reason the different wording is used? As a software developer it irks me off a little as I'd expect the descriptions for item effects to be standardized via some code path. Makes me think it's a different effect.

Welcome to GW2 and say hello to "consistent inconsistency" ...

 

Pretty sure item/skill/trait tooltips are just marked up text. They aren't being generated from the underlying code. This can be seen from the various cases of tooltips having extraneous items.
