Archers is generally a problem in the combat mechanics, however archers do just melt whenever skirmish ends. But with latest changes in the game the archers should be more of a gamble, if you bet everything on arches and you do not win the entire combat in skirmish, you will loose the entire combat with barely any troops left. If you guys feel differently after a week I might go in and change more stuff, but right now light infantry and pikemen should be the powerhouse troops but I might be wrong.
