with the server reaching max pop and having que's to enter the server there is not enough mining nodes to go around. it has taken me 3 days to reach lvl 70, yet over a week in i still can get past iron nodes.
spiting the server means less players farming
speeding up node re-spawn times means less time praying that 1 guild is not hogging every spawn spot for one material forcing players to buy is from that one annoying guild
