I mean... is it "git gud" to the person who thinks WB are too cost efficient, or "lrn2play" to those who don't play Impetuous correctly?
In case it went under the table - that was aimed at the "Warbands are too good" as in "Warbands are the only problem and my Posthumans/Mutts/Kamau/Dazer Minelayers are totally fine". They're good and they do a lot, but as they tend to not be Specialists and a lot of Factions have access to them in one way or the other, you'll have a hard time winning the game with them.
