If they do come out to meet you get into formation take out their tanks first followed by any priority targets(leader, best fighter etc). Every non tank needs to focus on one at a time once you kill them all or they fall back loot any of their corpses and heal up(never heal during a fight it's too distracting and marks the healer as a target). Continue destroying the walls if they come back repeat above battle until you take too many losses or you get in. Make sure you have easy access into the town incase you need to get back in following a death. Then proceed in destroying the guards and anyone respawning(eventually they will respawn somewhere else or log off). Heal up again then begin looting banding together anytime a guard respawns. If you don't have much time or live far away only take the most valuable stuff or anything you need (i'd go for armour and weapons to prevent retaliation). I'd also target one wall section or gate and damage it to around 90 then leave it hopefully they will miss it and you'll have an easy target if you need to come back. If you do lose any of your fighters get their stuff immeadiately so that when they make it back to you they can rearm instantly.
