Currently it’s the matter of who grinds beacons & c4 the most, so any рlayer without a big grouр and a lot of time will get beaned.
My suggestions: Give all walls/ceilings/floors certain tiers, and the ability to upgrade then, like in Rust. With certain tiers, not only the health increases, but it gets immunity from certain damage.
The first tier would be able to be damaged by anything, second tier would get immunity from melee weapons, third tier will get immunity from all low caliber weapons, forth tier would get immunity from everything but explosives.
For the explosives you’ll now need a certain material (for example, military grade wires) that will be time locked (which means you can only get it once in a certain amount of time, like a day, from airdrops, or a repeatable quests from an NPC). This way, heavy grinders will be timelocked, and it will give a bigger chance to solo, or lazy players. Also, nerf the horde beacon.
With such additions (if tiers don’t take too long to grind) raiding will be much more balanced. For once, people will actually value raiding materials and decide with caution on what to use them on, as well as it will give newer players a better chance at reaching the top on a populated server.
