The two big ones that come to mind are Thrawn and Piett. I was trying to think of good abilities they could have that are also thematic to their character.
I didn't come up with one for Piett but i was thinking a thematic ability for Thrawn could be something that modified the objective game. It could be one of the following
1. You may include three objectives of any color, including the same color
2. You may choose your own second player objective (seems way too OP)
3. You may reduce the objectives required by one.
I think everybody's go to answer for Thrawn is something to modify command dials, like an OP slicer tools, but I feel like this is a bit lazy and not thematic enough to his character, depending on how it's carried out.
What do you guys think? Do you have any ideas for Piett or Thrawn or any other commanders that haven't been introduced yet but are bound to show up?
