I certainly agree with the Baltic units. Bastarnae seem like merc-types to me... but the Sarmatians really do need some other factional infantry.

And I'll say it again, having to announce elephants is an EXTREME penalty to an already rarely-used unit that costs about a third of your total mnai. Most armies don't have extra gund-i-palta sitting around... but they will when elephants are announced, and suddenly 3k mnai trounces your 13k investment.
