The only thing I don't get is why everybody's whining about someone taking over localized resources.
All means to monopolize them is done by game mechanics.
And can be countered by game mechanics.
See a wall? Siege it.
See an alt HF. Place your own alt and try to be faster.
Resource owner are bigger/botted stats/nolifers/whatever - gather into huge zerg (game has over 500 online now so it is possible to organize 100 people in 1 place and fight if you are persistent enough) and bury them under the pile of your corpses.
If you are too lazy/weak/disorganized/autistic/larper/dontwannamesswithalts - just live with idea that some thigs in game require big effort.
In good old Lineage2 there were really small amount of people having epic jewelry. You had to spend 4-6 hours of uninterrupted online and grind mobs for 10-20 hours to recover your character to its level after that. And that's only to have a chance(if you win) to have a chance that jewel drops to be one of 40-80 people one of which would get it.
