I think the common guns are supposed to be basically as good as the Epic's
If there was a big power delta between guns then those that wipe and new players wouldn't stand a chance against the players with the best stuff
I've thought about this and I'm not sure how you resolve it.
On the one hand the game devs wants to make some equipment special, but on the other it'd be disheartening for players if they found that they died every time they encountered someone with a high tier gun. I don't think anyone wants to see entire lobbies get wiped out because someone brought a gold weapon in.
I'm not sure how you make the weapons worth something without making them OP unless you perhaps lock maps/areas behind a load out value - you can't go to a particular map or version of a map or an event without bringing in gear worth x amount. Maybe you limit free load outs to just one or two maps. Or limit people to a couple of free load outs per day perhaps.
I also personally think the ttk on the game means that any player who can approach another player who is distracted by anything at all has a practically 100% chance of killing them. A player going in unarmed and using melee only has a good chance of winning if they get the first hit.
I'm not sure if you should make weapons less effective at killing players, or shields more effective at protecting players, or health quicker to restore, or a way of self reviving from DBNO, but any one of those could make a difference. It'd mean people have a way of coming back from an attack, rather than just feeling resentful that they brought their good stuff to a map and lost it to a free load out stitcher 1 because they were distracted by an arc. Imo getting first hit is a bigger predictor on who will win a fight than the quality of the load out. There's little advantage to using your good stuff.
The whole thing is made worse because Embark make the expedition criteria be tied to the value of your stash. This makes people even more averse to using their good stuff because if they lose their guns, they've got further from having the 5m credits the game says you need.
In contrast, going in with a free load out means that you're always either going to lose nothing or add value to your stash.
Essentially, embark have created a game that asks players to get excited about gathering loot but everything about the game undermines the usefulness of the in game items players find.
I still like the game a lot, but I think some of the systems will eventually make me consider if I want to keep playing.
