If I activate the skill when the message comes up it says I can't use this for another 1 second. Very odd.
And also, last night when I was playing my MA, I died... but... my HP was on 13! Then when I came back to the rez platform I was on 5 HP... I never saw it drop to 0

And actually, another weird thing (hehe) .. I was in mid-battle -- MA again -- and I got a "Please wait, changing area" message like I was zoning! Mid-battle! When I finally "zoned" I was on the rez platform!
