I understand people's interest in giving them more flavor, but their flavor is that they come with 3 weapon slots and can upgrade smg's. That is already pretty unusual for a USF unit. The issue of giving them more versatility is that this is a buff. This would make the unit have more combat roles. Things like increased movement speed would be a huge buff because they could close the gap quickly and deal huge DPS. TFire up would allow them to ignore suppression partially. A new grenade option would give them more roles against infantry and buildings that they currently don't have (again a buff). Nerfs in other areas seem unlikely since the unit is expensive to reinforce, so needs to be very powerful as it gains vet to make sure you can afford to keep it around.
Careful what you wish for.
I'm with you in this, so it should be more of a sidegrade rather than an upgrade.
Ideas: (not all of them!)
Give them a satchel charge.
Bolster zook upgrade. Negates Thompson upgrade.
Remove self healing at vet2. Replace with smoke nade.
Add Royal Engineers or Paratroopers demo charge.
Nades already fulfills the role of antigarrison. I don't think satchels (Penals) are that scary to give them out.
Bolster: zook aren't crazy good as shrecks and they are on an expensive platform (kinda like PG).
Smoke nade is the biggest buff. That's why i gate it behind vet and replacing survivability traits. It would make it somehow different to Paras at least.
Obviously i won't give them remote detonation demos. I said Royal E. demos to differentiate it from Paras (although both are kinda useless
)
PD: i'm not sure with the smoke idea (more like a nope). I'll prefer either the bolster or satchel idea. Demos is kinda meh.
Sprint is an absolutely no IMO
