Car-4 is so incredibly good, it's basically the only primary you will need as a Technician ever. You can technically use LMGs or Snipers with the Mag Plus and use Bulletproof to soak more hits, but there is no reason to not use the Car-4 as you cover basically all ranges and with the right mods, can one shot SWATs.
UAR is pointless. Gold AK is a downgrade to regular AK 762, which is only useful for the one shot heads without any mods. Basically an autosniper that can be gotten at low levels. Still not very worthwhile. Commando 553 is a very very cost effective beginner gun, and is useful for stealth if you can only afford a suppressor on it. Size doesn't matter suppressor is best suppressor, and Gruber Kruz is the best silenced pistol IMHO. Some people prefer Crosskill because its a good jack of all trades sidearm, but why go for an M1911 when you can take a Walther PPK?
Oh man, the hype is going to kill us all.
Judge gun will become new Mosconi for stealth
Money bundle melee is new shovel (bonus if you can use the money bag if you carry one)
New mask. Ok.
Payday the Heist for free will mean that there will actually be more than 6 lobbies on a good day
Old Hox breakout for free gun b gud
Old Hox as a player would be even better. Every other character is shit. Dallas better kick out his little brother from the gang.
Single day Framing Frame could potentially Rats and Firestarter-tier money grinding.
FBI Files will probably be a continuation of the Payday Secret ARG from Payday the Heist. Potentially new clues that could link up to the unused ones from before?
Free gun. Ok.
Nuuu enemy. Better be CounterStrike level CTs. The pop flashes will block out the sun.
Day and night variants of heists. Potentially means more stealth options during the night.
Super secret.
