I'm not sure if it's just me or not, but it seems like the Stasis overshield Ballidorse gives interfere's with the healing from a healing rift. I end up standing in my rift, the overshield pops and i'm dead because i'm not regenerating health at all. It's a fun exotic, to me, and the 2x Stasis surge for just dropping a rift is nice, but it's not quite there yet with this bug.
