Peregrine Greaves, Astrocyte Verse.....Khepri's Sting. I'm not sure what exactly can be done to make Khepri's Sting viable, and I'm not a big fan of wall-hacks (gimmicky, unfair), but I know for certain that this exotic is borderline worthless. The only scenario in which it offers any utility at all might be in Competitive where you're able to give callouts to teammates based on self-smoke-bombing for wall-hacks, but even then, it only lasts 1-2 seconds and isn't nearly effective enough to warrant using instead of other Hunter exotics. Thoughts?
