go play minecraft, rust is tough and maybe it's not for you.
about loads of c4's, basically you don't have to use dropparty to change c4 spawn frequency, it just needs an admin who won't call airdrops every 10 minutes. it's required a decent amount of resources to make c4, because you'll need like 10-15 of them to raid a decent build base. go check it out how much sulfur do you need to make those babies.
but if you play on aidrop party server, one of airdrop has 5 c4 on it, plus some supply signal. so that's from where loads of c4 are added.
Rust is not tough, Rust is buggy, it's different.
Being good at building in Minecraft actually matters, because you can build your base underground or hide your chests behind walls etc. Building in Rust takes NO SKILL at all, all you have to do is building an ugly maze with tons of metal doors inside, and even then, you can get raided EASILY.
C4 is not the problem, the problem is people abusing of bugs to reach the last floor of a base with boxes and barricades.
