Snapshot is one of those upgrades that on their own isnt that great.
When massed, they can be a real problem
When massed AND on mobile platforms, they can be a bigger threat than the main attack.
Two Greenwings with Snap, PTL, VT, Chaarrefit, and Title are a staple for my rebel lists. So many people make the error of assuming theyre just a distraction and they gun for Norra, Rey, or Hyperdash theyre paired with. Then the greenwings shred them while the "real threat" just plays keep away lol.
Its easily one of my favorite upgrades because its such an underdog ability. NOBODY expects it to actually matter until it causes you to basically kill yourself by flying into my face. Then they start playing super, super defensively doing all they can to avoid that front arc, often losing their shot in the process and i still get mine or i can chase them now with ease.
