bleed effects

Miiya - Raging Tide

i remember reading somewhere that the bleed effect from draw blood and piercing winds stack. i'm curious as to whether the bleed from draw blood would stack with a barb's flesh ream, or would it "overwrite" it?

thanks in advance for any answers. b:thanks

Taleon - Heavens Tear

they stack yes

Hypnos - Raging Tide

all DoT from all MMORPG stacks. Only same buff-placer overwrite each others.
