Every time you do a wound, you get a bleed on the enemy if you select the lvl 5 talent Rage. Sadly that bleed gets overwritten by your next wound. Which means you never get a single tick of the bleed if you wound spam faster then once a second. This makes the talent useless for wounding.
Second bug, when you get a bleed from the actual bleed affix, it also overrides that bleed. So the bleed of the bleed affix also gets removed before it is useful.
