Has no appeal for my defensive wars, Armored Fortress wins out on that 9 out of 10 times for me, maybe if I experimented with an offensive war, and even then it's doubtful, because then I couldn't spec into Rage tree, rendering my offensive war very weak, just doesn't seem a good contender for the other top-tier war skill which (in my opinion) compliments the point of a war gladiator.
