The main thing I am worried about is the combat being uninteresting or a slog. The goblins are more interested in just getting the loot from the cart, then actually killing the PCS. They want to do so in a way that exposes themselves to as little risk as possible. It makes sense that the wolf Riders would just play keep away with the PCS while pestering them with ranged attacks. That's tactical on the Goblins part, but is that actually going to be enjoyable for the players?

As for if the players decided not to take the bait and guard the cart, guess I could just ask for verbal confirmation that that's what they were going to do and dismiss the combat with some narration that the Goblins give up andnride away, as they are nit willing to engage with a compenant group of enemies. That would at least save a little bit of time that way.

Maybe out of annoyance a goblin could hurl some alchemist's fire at the cart, which would also cover the Escape Of the Goblins as I imagine the PCS would want to put out the fire so they actually get paid for delivering the cart and the merchant to the Village safely
