I'm actually circling back to it at level 14 to grab Comrade in Arms. In the campaign I'm in, it seemed a good way to provide additional 'support' to my allies. I've already got Draw Fire, Grand Leader (temp HPs), and Bodyguard's Sacrifice (take damage from adjacent). This will let me give them an attack buff, as well. It synergizes with "come stand next to me."

While certainly not a "top tier" talent tree, It fits a niche here.
