Weird question to answer. The usual “it depends” is there.
A Nomad is better of executing than sniping though if you’re considered playing with skilled players so that Markza would definitely go into the hands of the Markzman. Nomad can just chain-execute enemies even without a Lancer or Retro. Marksman can also pickup ammo and trade all his Boltok ammo to Nomad.
Maces go to Striker, Blademaster, Protector. All of these technically don’t require a weapon to be viable in Escape but it helps all of them (Striker probably the most because that’s the only way to apply bleed to an enemy).
Gnasher goes to Infiltrator and otherwise Protector and finally Slugger (stunning effects) and then pretty much any other class who may need some bullets. Don’t forget Deception with Architect. Walking around an enemy and shoot it from behind is very easy to benefit from an additional 200% powershot every time. Generally nice against Sires. Of course other classes like Blademaster or Nomad have boni with that weapon too but their respective cards are generally never used.
Overkill goes to once again Infiltrator, otherwise probably Mechanic or Robotics Expert and then any other class. Infiltrator is the only real class to greatly benefit from the Overkill. The two Engineers only have a slight benefit from it.
Longshot goes to Markzman primarily and then any other class that has some benefits of it. Pretty much any class can use a Longshot, it just depends on who may be the best sniper on your team really.
Embar is the “it depends” one, generally I’d say Markzman first (e.g. The Split) but it can also be handed to a Mechanic or Veteran for instance. It’s generally a nice gun simply because of the stunning effect.
Markza is also a “it depends” one but generally I’d give it to Markzman first and then any other class. Again a bunch of classes benefit from it such as Anchor and Nomad but both of these two have better means playing a different playstyle (Nomad with executions, Anchor with the Boltok).
Boomshot goes to Demolitions and then Tactician. Demo does more damage than Tac. Tac can play with any weapon due to Disciplined.
Lancer GL is the same with Demo and Tac being first. In theory, Tac would be better suited with it due to Disciplined but I’d still hand it to Demo first if there really is one in your team.
Lancer goes to Nomad, then Veteran, then Combat Medic, then anything else (maybe Brawler next due to burning rounds). Nomad’s execution I’d consider to be more viable than the damage from the Veteran. Combat Medic has a rifle buff via Passive already hence I’d consider that class to be third in line.
Retro Lancer is the same concept as above.
Dropshot goes to Pilot, then Tac, then Demo. Pilot has the stunning ability and additional damage from it, Tac could use Speed Loader with it technically and Demo only gets bleed from it really. (Relic Dropshot is different - here it doesn’t matter who uses it, preferably a class that doesn’t rely on weapons)
Enforcer goes to Mechanic, then Robotics Expert, then Tactician, then anything else. Mechanic completely melts enemies with it, RE gets to have reduced bloom making this a laser gun for him essentially. Tac because of Disciplined with similar effects to Mechanic.
Hammerburst goes to Tac. Once again Disciplined makes this gun do wonders. Brawler can also benefit from it greatly with the burning effects.
Torque Bow to Gunner then probably either Markzman, Tactician or Robotics Expert should get it, potentially Demo too. Gunner has good bleed on it. The Markzman will have to do headshots with it while Robotics Expert MUST NOT do headshots with it. Tac and Demo because of little bleed.
Buzzkill goes to whoever has no weapon or no bullets or whatever. Generally a gun that’s not too viable and almost never used.
Mulcher goes to Gunner.
Trishot goes to Gunner and otherwise Mechanic (reduced recoil, it works pretty well on The Link).
Cryo Cannon euh… I guess anyone can use that really. Hardly ever used.
Salvo goes to Tac, then Demo or Mechanic. Generally a very powerful weapon.
Claw can be used with anyone really. Sure Blademaster gets a buff card but it’s hardly ever used. Probably Tac benefits the most from it - Disciplined FTW.
Scorcher goes to Brawler if you really want to use it…
Frags go to Slugger then Demo then Tac.
Flashes for Nomad then everyone else.
Smokes for CQC classes (whoever randomly gets a hold of it by meatshielding Elite Hunters).
Shocks for Robotics Expert then Slugger. I believe the damage for RE is slightly higher than Slugger if I’m not mistaken.
Flames for Brawler.
