Ok I only will be agree if Balin gets again at lvl 3 his op leadership which brings 50% of armor, if not i prefer my teleport
Any Way, you are right but think in the expedition as a travel around the map, but it is done very quickly ;D
Another battlewagon isnt needed, but if this battlewagon brings leadership could be interesting.
i think a strong leadership or a hero buff, fits more with him.
