No exotic slot, horrible horizontal spread, outright bad against lateral movement, delayed explosions, the gun itself isn't hitscan, delayed trigger, 2 shots on spawn, and you still need to hit 4 bolts through everything mentioned above. You have summoned me.

Prefer Erentil and is the only other fusion to match Telesto's damage, Telesto's bolt damage is just more consistent. Touching that weapon isn't going to change anything, you'll either bitch about Erentil or shotguns. Unless you're shotgun ape mad about get it shat on.
