Archers and minions are the exception because they can hit from far and above the walls and take few time.
Pekka, draks, wizard (fragile) , balloons ( fragile) all these silly troops cost much in time and elixir while they are uncontrollable.
Barbarians suck because they are weak and uncontrollable too.
These best are giants and gobelins and healers.
So barbarians are not the worse so barbarian fetichists can cool off.
