Guild Wars 2

Has anyone done testing into how this works, now? I know some people mentioned it before the patch hit, but I haven’t seen anything since.

Does it just add 2 seconds to one Burning stack? Does it extend ALL Burning stacks by 2 seconds? Or does it simply not work anymore, period?

It tacks on an extra stack of burning that lasts two seconds beyond what you have already from what I’ve seen.
