On our server we have very rare C4 - uncraftable, about 0.5% drop (x1) from zombies, about 20% chance for 1-6 to come in an airdrop crate (which are only 2-3 times each real day). This makes ‘online raiding’ even more attractive, since if you only have enough charges to blast through 2-3 doors, catching them with the front door open (coming or going) could be crucial to actually getting loot - not to mention of course you get what they may be carrying/using!
Of course people are doing to use whatever obvious strategies exist in order to get the maximum payload with minimum effort and cost (time/resources) - whether that’s offline raiding, or building up a few sets if stairs to get into your base through a design flaw, rather than spending their precious explosives if they can avoid it.
Devs have already acknowledged that offline base defence is a focus area for them - try to relax a little and trust that improvements will arrive in the coming weeks
I haven’t had that problem on my server, at all. Two main reasons for that, the first being I’ve built my reputation from day 1 as a Fair Play admin… I started with a hatchet and nothing else, early all my gear legitimately - and we’re a hardcore settings server with no high-end stuff creditable, and drop rates for good items in the sub-1% range. If anyone accused me of admin abuse, I’m sure I’d have half a dozen regulars telling them to stfu without me having to lift a finger
It also probably helps that I’m a shitty shot in a firefight I can pick off a pig or walker with a bow at maximum range (max view distance) in 2-5 shots, but when I get excited I’m all over the place haha
