The reason players sit in Astro and stuff is cause they can't afford the guns, so here's a solution.

1.) Buff the jobs to give more money, and make them more appealing. This will drive players to do them more often as the reward will be much more worth it

2.) Lower weapon prices, so those players can actually afford the weapons to have a chance agasint the higher tier guns

Afterall, the players currently with high tier weapons (like myself and the entire experienced community who doesn't stay at start/Astro) have earned these weapons through grinding events or doing the jobs. I used to get 20k a day doing pizzas, it isn't hard.

You want to make the game more fair? Then this is a way you can avoid angering the entire experienced community and it'll help out the noobies
