Also, for what it's worth remember that snipers that are on the offensive (moving) are incredibly costly to the opponent. (# 3 wits to make, +1 to bost, +1/move) If a boosted sniper moves just three spaces it costs the same as a bombershell.

So while they can be a huge pain, remember they're also an opportunity for you to cause a huge pain to your opponent. That's a lot of wits that have been sunk into a very fragile and inagile unit.
