Yeah, I mean like every other sandbox builder whose building mechanics allow the freedom and variety in building the same way as Conan Exiles.
Because there’s no better game to copy a solution from than a game that doesn’t have the problem you’re trying to solve?
Easily. You underestimate the motivation and resourcefulness of griefers. But even if I can’t do it with 6 claims on main, I can do it on an alt. Even easier on console, where alts are free. 
Oh, it’s all right then. As long as you personally don’t care about some aspects the system you’re asking Funcom to spend time developing, it won’t have to handle them 
Why does it matter? This is precisely why I mentioned pet peeves in my post. Everyone has some. I have mine, too. But unless I can show why they matter, they’re not reportable.
And “I just don’t like it” or “it’s unnecessary” is not an argument that matters. Nobody cares what you like or what I like, because the game isn’t there to cater to one individual. And as for “it’s unnecessary”, so is having a horse. In fact, more than half of the stuff in the game is “unnecessary”.
So explain why it matters if you want Funcom to care about it.
Negligibly. They’re not resource intensive in any way.
There aren’t. If you think there are, point them out. If you think there should be, explain why, in terms of negatively affecting other players’ in-game experience.
They didn’t. There’s a reason people kept asking for moderation. Griefing was rampant. Performance problems due to overbuilding were also notable, but not as notable as they became after Funcom implemented mounts, but that’s a whole 'nother can of worms.
Thing is, none of us expected Funcom to go overboard with moderation and then keep bumbling and fumbling it until it became a Kafkaesque nightmare we see today. For my part, all I wanted was to have an easy way to deal with griefers and trolls. Someone walls you in on a PVE(-C) server? Call an admin to smite the griefer. Someone paves over all of the Shattered Springs? Call an admin to smite the inconsiderate jerk. Someone blocks the entrance to a dungeon? Call an admin to smite the troll. Someone deliberately clusters 500 torches in a small space to make everyone lag? Call an admin to smite the asshat.
But this whole crap with “don’t build purely decorative builds”, “don’t build walls too far from your base”, “don’t block a POI”? All of that is unnecessary. Yeah, I don’t like huge highways and bridges, just as I’m sure there are people who don’t like being unable to get an achievement for discovering the whole map on a particular server, but this was never supposed to be about dislikes.
That said, I wouldn’t even mind the overly restrictive rules if they could freaking deliver by doing a decent job.
Precisely. And what makes it worse is that none of these proposals would solve that particular problem, either.
It’s actually very relevant. I don’t know where people get the idea that claim itself is the problem, but it’s fascinating to see them get fixated on that and never let go. It’s not the claim, it’s not the build, it’s what they do to other players.
Creating sources of extreme lag was one of the very real problems before the rules. Ironically, it can still be a problem because Funcom dropped the ball both with the rules and their enforcement.
