Oh yeah, I love Impeding Shot and Squad Discipline, but compared to Cody and Fives I don't feel like Brothers in Arms atm is competitve -- the turn meter is negligible for what it costs (someone to get crit) and the only part that seems useful is the extra hp which meshes with echo's By the Book, but that feels like that's all it brings to the table. Replace it or Subdue with a Burst Heal (or another regen ability) and I feel like he'll be better.
He may be a leader by rank, but he was never in a position of command in the series, he was always subordinate to Cody of Anakin in every single episode, even Ahsoka and Obi at a few points.
I look forward to maxing out my clone team, my Clone Sgt right now hit his first 4k crit today on an equilevel enemy.
