Guild Wars 2

I run with Superior rune of vampirsm, so when I fall below 10% health I turn into mist.

Problem arises when I enter plague and then fall below 10% health I turn to mist, for a few seconds, but when I exit that mist form I am no longer in plague.

I’m not sure if that is by design, but is sure annoying when using plague as a form of escape from a large group of enemy.

I agree with lupercaleb, seems this is by design.
