What class should carry ammo packs?

[exLupo]

I went with LA due to elimination. Here's my line of logic.

Who needs ammo? Anyone running out of ammo.

Whose ammo has the biggest bang/buck? MAX.
Self sustain on the strongest shooter is out.

Who already has a type of sustain? Medic.
Multiple sustain types synergize too well. See PS1. Medic is out.

Who of there remaining four play with others? Engi, LA and HA.
Infil is out. While sniping needs sustain, everyone does. Better to be with the group relevant classes.

Who are mobile and operate away from resources? LA and HA.
Engi would be more likely to be less mobile or tied to resources. The point of ammo packs is to resupply in the field. Engi making ammo is ok but that's not the point of ammo packs, separate issue.

That leaves LA and HA. To me, LA edges HA out because of the weakness of its armor and weapon. In a shooting brawl, HA will be the more potent unit both from output and survival standpoints. The concern that dropping ammo packs will lead players to solo is legitimate. However, if someone is going to be doing it, I'd rather it be the weaker unit. From the streams, LA seems to be limited less by its ammo and more by its lifespan. Increased ammo capacity would be helpful but camping with MA didn't look too impressive and there's no place one LA can get that another cannot follow.

To me, LA is the least worst option. 2142 has made me loathe unlimited ammo packs but if LA are limited to one or two, their loadouts can be lightly tuned to consider people using ammo for themselves only.

If I were to pick, I'd order it like this:
1) LA with 1 or 2 packs.
2) No packs.
Everything else.
