Definitely. Need standard Burst HMG and Assault MD, too (any others?). Doesn't make sense being forced to run 20k variants on otherwise standard fittings.

I would also love to see the camera sight back on the scoped AR's. Pretty please?

I was watching some old videos yesterday, realized we actually had more of these variants at Standard back in the day than I'd remembered! We need:

Tactical AR - Had it.
Burst AR - Had it.

Assault SMG - Had it.
Burst SMG - There was a Freedom Burst SMG at some point in closed beta, can't remember if there was Standard/Adv.

Assault Forge - Had it.

Assault MD - Don't remember having it.

Burst SCP at Standard and Pro - Had Standard, can't remember if we ever had Pro.
Breach SCP at Pro - Can't recall it being on the market, but something is telling me I saw one in a match at some point, maybe an Imperial?
Swear there used to be a Specialist and the IA5 Tac available on the market, too.

Burst HMG - Don't recall having one, but I didn't use HMG until about a year ago.

Specialist Shotgun - Had it, might not really be a priority, but there's Adv/Pro Specialists so we need it back for consistency!

Breach Flaylock at Adv/Pro - Don't think we've ever had them.

Charge Sniper at Std/Adv - With the whole :Rail tech charge up" thing, it really should be the default sniper variant, imo, and should be represented at all levels. Pretty sure it wasn't Pro-only when I first started playing, as I tried it out on or around the first day and I know I didn't have Pro + Proficiency Snipers.

Anything else? Most we've already had, just need reintroduction with appropriately tweaked numbers. Only a couple would have to be created "from scratch", and even then, it'd just be a "subtractive" name and numbers, more or less. More standard level variants would make the game for low SP/poor/cheap players much more diverse, increasing flexibility and the ability to experiment at a lower meta, while the other missing variants would help normalize progression for existing variants, both good things.
