the social interaction stuff wont work if...
the social interaction stuff this game is proposing and relying on wont work unless the servers are much smaller than the 50k accounts and up to 10k players currently online.
for example, a need before greed system, will go like this (on a group of random strangers): item drops, all need always since you can sell items and nothing is soulbound. one guy actually needs the item to equip right now as an upgrade.
now this can work out fine, where he asks winner and is traded for free, or he is declined. for the social dynamic to work, you need to see alot of the same people, you need to know that your reputation even as a lowbie leveling matters, and i dont think this will happen on such big servers. i recently played wow classic on such big servers, and there were so many people to choose from, that nothing social really mattered on the high pop servers. you dont like someones dps, just kick replace, so what if he ignores you? you have potentially 50000 others to choose from. note here, that the original wow vanilla had alot of the social interactions aspect and it worked very successfully, but back then due to tech constraints, servers were about 1/3rd to 1/4th of what they are on current wow classic or what is proposed for AOC.
even in real life, compare the interactions of humans in a village vs a large city. you will find tons of antisocial behavior in the large city, that gets unpunished or even rewarded, while the opposite is true of a village. also to note, that some experts have noted how for thousands of years the average size of villages of humans we have found are around 150 people, consistently. it seems our brains are just wired to be able to recognize and know alot about, roughly 150 people, so we are not only talking about personal preferences, but biological and psychological constraints when we decide the size of each server.
so, i would like to ask that alot of thought, research and testing be done, and possibly rethinking and change the sizes of the servers, as its important to see alot of the same people, for social dynamics and social interaction to matter and be successful.
