Seriously building will only bring negative things.
I ve played many survival game and building bring only power to the most active player and unbalance the game.
Since i m over 30yo, i play "just" 3-5 hours each day.
When i was younger, we played 3 people on the same account (from different country) to farm 24H each day (8 hour for each player) to make a huge stuff and farm real money. Also because we had a dominant position on a game that favored big players.
By allowing building, you risk to increase the gap between players, and maybe even increasing the IRL blackmarket that exist on some forum that i would not mention.
But for real PGM, i understand your point of view !!
Anyway, i m playing since something like a month, and i want to thanks the developper (but also the old players, without them, no game! / and also the forum team member) for the game as it is currently, both open & survival world, the game is safe from cheaters, well balanced, really one of the game i enjoyed the most over last 3 years.
Finally, i apologize for my limited vocabulary !
Peace (not in game) & Have fun
