Love the new Command and Browbeat. This route of buffing useless skills without gutting the good ones is definitely the direction, in my opinion, your other mods could have gone with as well.

The MaA is always an essential teammate in some of the more specialized set ups, I can appreciate a means of diversifying him to fit in some less niche set ups. I find the reduction of Crit to Rampart curious and the removal of making enemies receive a higher crit chance from his kit altogether. But I'mma give him a try either way.
