If they fix the Time Stop bug (if it’s a bug and not a nerf) then it’ll be awesome. You can use 72-sec SG to clear rocks and then the first TS to deal with the first attack wave. You’ll be partly giving up on your other calldowns (DP and BH) for the rest of the mission, but it’ll be a worthwhile tradeoff.

If they don’t fix, and it’s a nerf to TS, then I’ll only use it occasionally.
