Placeholder weapon could be interesting on support commanders (and would allow com to escape when rushed down by a mace or something like that).
Straight up newton would be too stronk imo as it would make commanders immune to jack, scuttle and most bombers.
Melee weapon on commanders could be real fun, especially on recon com (as it already can jump to poke someone to death)
Arguably, HL style crowbar could be a nice skin obtainable for kudos.
