Been playin HC and gotta say, yup Relentless beats Bloodthirst in every way. How is it no one uses Relentless in SC PvE? Instead everyone uses Bloodthirst?
In SC, we have higher damage and lower health pool. And also we don't really care about dying.
Because even with 50% damage reduction you are going to get 1-shot at 20% life. Otherwise you just have too much EHP for softcore.
