I like Wicht's versions. Think about it...if they get the jump on the party, whick looks likely the following would occur:
1. 6 shots at +7 to hit (hits AC 17-18 on average)
2. the party is flat-footed (who knows what this does to their Dex, but it will probably hurt)
3. Each shot that hits (assuming within 30') averages 11-12 points of damge
4. Some type of poison that could be havested by the goblins would require a save to be made
- Giant Wasp poision is DC 18. d6 Dex, d6 Dex
- Large Scorpion is DC 18, d6 Str, d6 Str
- Carrion Crawler DC 13, paralysis, -
Tactic - place them in either two groups of three or three groups of two, each group targeting a different PC. This could potentially ruin 1-3 PC's day if hit and a failed save or two is made.
If getting within 30' is not possible I would go with straight 4th level Fighters with bows and go for Rapid Shot at long ranges. You still need to be within 30' for Weapon Specialization to work so why bother if your outside that range anyway.
I'd definetaly add poison to the list of things they would do though!
