The NA-45 is actually really good. Slap iron sights on it, exo jump over the enemy and fire both shots at their feet from the air. It works for me almost every time. Plus, it's great for objective gamemodes.

XMG is fantastic for objectives too; just dig in near an objective and mow the enemy down as they come.

MDL is generally useless for most gamemodes but I found it had a use in Hardpoint - especially in enclosed spaces. Spamming grenades into buildings either kills everyone inside or makes them evacuate pretty quickly.

EPM3, from what I can tell, is a slightly more powerful version of the MK14. It's not terrible, but there's not much reason to use it.

AMR9 + rapid fire is great at close range. Especially the Elite variants.

Tac 19 and S12 are fine, I don't see the problem with them.

I barely touch the Bal, ASM-1 or AK-12 and I fare just fine most of the time. Sure, there are balancing issues, but to give credit where credit's due, I think Sledgehammer has actually handled it quite well (i.e. patching the S12, XMG, EPM3).

As for supply drops, I have no idea how these things work but I'm pretty sure they're not completely random. Since I got the game, I've been bombarded with MK14, AMR9 and Ameli variants, as well as Obsidian Steeds, but I've never once got a Speakeasy or an AK12 variant, and I barely ever get IMRs or MORSs.
