Not a bug per se, but as reported by a fellow coalition player the translated French text for Ravager’s ult reads “vous gagnez 5 points de vie” ▬► " you gain 5 life" rather than “lose 5 life”. It’s likely that the same reversed translation error is present for each progression level of that 3rd ability,
Apparently he discovered this the hard way by trying to use it to gain life during a match…newer (French) players would likely also have the same nasty surprise if this isn’t corrected.
