Yeah I started off with the XM4 and kinda abandoned it for better guns.
I recently started trying the Krig which feels excellent. I feel confident engaging enemies with it, it's faithful and solid.
The Qbz I used in the beta a lot and it's a beast. The full auto FAMAS looks good, only recently unlocked it so haven't quite used it.
My most used guns are M16,MP5,Stoner.
My go to class is just abuse. I run lawbreaker. So it's essentially overkill. M16 w/ MP5, then I run Flak jacket. Gung ho and ghost. Because you can muddle and mix perks.
I sometimes swap flak for tactical mask and take out gung ho for ninja.
But running 2 primaries I need the gung ho for the faster weapon swap.
I will have other classes once a weapon is maxed. I will probably have an AR with 7 attachments, ninja and a launcher to combat lack of ghost.
I will also run a perk greed class soon, so I can go with Flak/tact, Scav, Quartermaster, Ghost and ninja.
I do still have a danger close class with double stun and X2 frags.
The Stoner is slow, but damn it packs a punch. Seriously, apart from the slow ads. It shreds for real!
Only gets better once you start getting speed attachments. It is really tasty and slept on imo.
I use it with cold blooded and a launcher for anti air. Just recently tried gear head with assault pack field upgrade to rack in the score.
Shooting down UAVs are 100 to your streak, add a few kills and objectives. It's easy to get those attack helis out. 😁
