Make a heavy class that has bigger weapons and more health but the drawback is there slower this would be a good way to implement more lmgs and possibly a minigun and would also make the game a lot fun imo giving people opportunities to push in different ways and overall I see no downsides to adding this I think it would just be really cool to have a minigun in the game and a tank/heavy class.for there gadget they could have portable shields they can put down for cover.i don’t know about all the perks but one I thought of is if there on a kill spree they get a sudden boost of adrenaline after 3 kills making them way faster.
