Guild Wars 2

So after an elementalist is downed they have the option of doing the spell called mist form (i think ). This spell basiclly turns you into mist and you can move invincible for about 3 seconds. But in WvW after I am downed once, use mist form and rally everything is okay, but after I am downed after that (within the next about 10 minutes) and use mist form if anyone attacks me when i exit mist form I am dead. Even if nobody attacks me you fall to the ground and all the HP just goes away. This bug is not just with me since i checked with a couple of my guildies. This bug has been there for a while but I thought somebody would report it by now and A-Net would fix it but since nobody reported it here I am. I am also playing on Blacktide (EU) if this means anything to you

Check the elementalist forum each time you use mist form a stack of downed penalty is added already reported ages ago.
Dunno if wai or a bug hope the second one
