It isn't cumulative. It is reset to the 7 (or so, can't remember exact how long it is) minutes each time you die. If you die 10 times in a row, your maximum weakened cooldown will still be about the 7 minutes.
weakened coldown isn't afected by the way you die?
AFAIK if you suicide bomb yourself it is longer... whats does it have to do with this thread Ok, if suicide bomber explodes, he has his weakened and even if it will be below 7 it should cumulate up to 7 again :p The eventual death on weakened is caused by weakened (most probably) It just adds to grief
I don't think it is cumulative. Well, if it is, it should be changed indeed.
Like I said, it isn't cumulative. But changing it to 5 minutes if you weren't weakened before, and 7 minutes if you were already weakened sounds fine to me.
