Huh? I can put an Umbra or Nexus in a fireteam, too. They could put him in Mormaer or Highlander Grey armor to get Shock Immunity. But overall, Shock ammo is far too common, and the new units with NWI are given Shock Immunity, which defeats the point of Shock ammo... that whole rules space needs to be rebalanced, but CB is too high on making staff self-inserts and new golden child sectorials. Removing Shock from SMGs would be a good start. Regardless, the game is tilted towards having to play safe with your Lt for a number of factions, and it would be a significant boost to CHA's power for that to be the case.
