This is a very easy question. I played on official server for 6 months, there was no admins or protections, so server was full of cheaters, if you go to any populated area - you would die from their aoe killing cheat, or see somebody flying around, and other stuff like that. In that server - survived only 2 types of people, who was not using cheats:
1) Big groups, who was able to build big bases with ease and hunt on smaller groups and single players, if cheaters destory them - they just build another base very fast.
2) Smart people, like me, and one friend that i found on that server. We don't go to the populated areas, we don't build our houses in front of big gropus. We hide, sneak, scout, find weak places, raid them with protection (building own rooms inside the house), and only then use that resourses to build our own big bases, that cheaters could never raid (they tried on my base 5 times, last time they used more then 80c4 and still got almost nothing).
And how do we defeat big groups and cheaters? And here i will tell you the definition between weak and strong. Actually, strong players is smart ones, who understand how game works and what they can do with it. Weak players depend only on their numbers, cheats, or shooting skills, without using brains. There was a two wasy to defeat them:
1) Scout, follow them to their house (may take a days to complete), look trough gaps, calculate room with loot, raid (if they are cheaters - wait for them to go offline first). Was good raiding cheaters - most of them was incredibly stupid, they big huge bases, but left holes in deffence that could be easily used for raids. For example, i got to the last floor of a big house just because i built shelter on the rock nearby, jump on it with crate, and blow a wall from that position.
2) Sabotage their houses. Why i need to raid my enemies, if they so much retarded to build huge tower with only two exists, and didn't even block it with pillars? I just build walls and celling around - and they cannot leave or enter base anymore, not without c4. Or destroy stairs and build celling - all upper floors are blocked forever! This, and many other methods of sabotage - i found the perfect and most interesting way (better then blowing walls, because it needs from you to find weaknesses in their deffence) to deal with your enemies in this game.
So, the answer to your question - weak players is stupid players, they can have numbers, reflexes, expirience, even cheats - but still make a stupid choices were easy defeated by a single players. Seriously, for all time i played on that server alone - not a single guy (or group, or group of cheaters) was not able to raid all of my rooms, take all of my stuff, and i, sometimes alone, rarely - with help of a friend destroyed everyone in huge area around my house, only decaying ruins was there.
Your main strength - is your brains, that will help you defeat enemies better then anything else. And now... now they are making game for the people who cannot use their brain properly, so they need magic shields that prevents sabotaging, map to find each other, locks on crates (to make raiding less profitable), and else. I will be not surprised if they will announce pvp-free zones next.
First of all, it's hilarious to hear you call yourself a smart person. You obviously have autism. Secondly, you are saying you beat big groups by following them to their homes and griefing them. That's not really 'beating' them, is it? The goal is to get their stuff, not just ruin their base, right? Nothing you've mentioned is novel. How is that impressive, and how does it make you a strong player and others weak? Also, there's not really many houses you can just build random walls on to that would keep them stuck inside. That's why most homes had mid-pillars.
