2 hypothetical roles I haven't really seen yet?

BAR is a team game and it's my favorite aspect of this game. That said, there's 2 roles I'm surprised to not really be seen employed in games.

The Commander

Basically, the players entire focus is attempting to direct the chaos. Ensure radars are set up, help a commander recover from setbacks, suggest ideas for an overall strat and so on.

I've been getting back into watching games and possibly start casting again and one of the key times I see players be frustrated is getting rolled over by the enemy team and having to basically start over from scratch when it would be faster to be gifted infrastructure to bounce back in their role. A commanders spot could help with that and using scoutcraft or recon units specifically to try and watch the battle.

The secondary thing this does is can help get other commanders to influence other areas of the map or even pivot their role to do something else such as changing from sea to air or flanking.

The Eco

Eco scaling jumps at T2. A rough sketch of an outline would be this player basically being boosted to get to T2 as soon as possible then focus on upgrading Mex's and their energy generation, keeping their spending somewhere between 50 - 80% of their income and letting the economy spill into the other commanders.

What's everyone's thoughts on these or role ideas you've thought of but haven't really seen?
