I have tested the new Crucible for a few runs and I found 2 Bugs:
1: The perks that resurrect you when you die do not seem to work at all for me. Picked them on multiple runs and did not get rezzed by them or at least I could not notice them taking any effect.
2: There is a negative perk effect that drains your health when you are using focus. That healthdrain also occurs when you are shooting a bow, even thought normal bow shots do not spend focus.
