That would be fine, to stop botting, but pointless to control the economy for normal players when you can just go and instantly find another it makes it pointless.
Unless you then somehow control the "respawning" of these nodes, which of course must be per player as otherwise they will just be camped. At which point you just have a personal timeout in exactly the same way.
As for crafting, it was never meant to be a "big" gameplay element, its just one of the easiest to do game play elements to get working.
Yes, one of the problems is that ore/minerals are waaaay too common... I dont know if the engine lets you, but can you control the encounter areas? For example every square on the worldmap would have 1 specific layout, not allways changing when you enter it like it does now. This way you could setup a few nodes around the world that would control the economy perfectly because it limits total resources. Ofc this also raises other problems like gangs camping the node. Note that they cannot benefit from this because for them, the node is depleted, so they cant gather resources from it, just to bug others. Actually when i think about it, no change there since i get PK-ed anyway while farming the same node over and over again
Or even better! Remove resources from REs alltogether, and setup small custom areas like the ares military base, that contain nodes, and name them mines, woods, junkpiles, mutated..corn...like..plant...fields, etc. A player needs to travel from mine to mine to gather resources.
Again, this would be quite fatal to the averega miner, but think about the gang wars. Gangs fighting for control of mines.... If you think about it, it makes sense, the great war started because of low resources anyway.. I dont think any country would invade others and start a nuclear war that exterminates 90% of humanity if they could just go into the wilderness 1 "square away" and find ore, minerals, wood, fruit, etc to make miniguns, ammo, even fuel...
A grand example is the ghost farm... A whole field of fruit and you cant gather them?? Why??
Summary of my pov: Limit the resources the world has to offer, Not the players. Needless to say this also limits crafting in general, as no resources means no end product for the crowd either. Even better: Low amounts of goods on the market(game badly needs an AH.) means higher prices, high amount of goods, low prices. You, the devs would have TOTAL controll over the ENTIRE economy, by limiting the resources.
No alts would solve the gangs problems.
No Bots could automate the gathering.
I seriously cant think of a counter argument, other then implementing all this is hard, but i think its possible.
