We have troops who go after defenses, we have troops who go after loot, we should have a troop who goes after townhalls. Obviously it can't be a drop in a bucket but it could be possible to get a townhall snipe on a base with the townhall centered. Someone could design an army around the townhall seeking troop, requiring spells too, if they wanted to get the townhall, without a doubt; that would make it less apatizing, just because it is essentially a complete army anyhow.
