On your opinion, the projectiles going through hired units seems a bit bad. It would create lots of OPness and exploiting. Instead of designing archer slots, all you'd need is a big tank unit(like a Troll) stuck or on 1-block guard mode, with archers behind it. The enemy archers would hit the tank, and your arrows would go right through.
