You can't choose 1 for one faction and a different one for the other. Its either an lmg for both or an AR for both.
Ugh. I love a ton of things about this game, but I hate what they did with the weapon system. IMO, all weapons should be accessible by all factions. Making weapons faction-specific guarantees imbalance (just look at the GRN unlockable pistols for a perfect
example. 5 unlockable pistols, and four of them are for the Ghosts. And, the Ghosts get the Defender, which is a pistol that shoots shotgun shells). Making the decision point non-independent makes for a lot of frustration.
417 and AN-94 no question. Type 95 is utter garbage compared to the RPK and PKP, and the Stoner is outclassed by the MK48. The 417 is a superb gun too, as far as I can tell.
I picked the LMGs and I completely regret it. I'm definitely respecing once I hit 50 to change that.
Unrelated question, can you pick these weapons separately by faction? I've been wondering this but haven't had a chance to check yet, but could I hypothetically pick the AN-94 for Bodark and the Stoner for Ghosts?
