Hello! you can read 5-7 last pages in autogrinder thread (posted my formations there). I think its necessary to have 1-2 melees in every skirmish(atilla(5+), druid(5), general(4-) are the best), 2-3gunners + hwarang are helpfull too, 2 healers can help too (i am using shaman + oracle, ora+vamp is better).
