By your very own words, The GMs are biased to non-aligned players as Neutral players cannot participate in the Trial of heros. They are also biased against poor players because poor players obviously cannot participate in the Auction. Then you have GM's being biased to the low leveled players by having events that they cannot enter because of the minimum of level 70 rule on most events.
Creating a method to promote a system that is barely used isn't biased. There is an aspect of the server that isn't used nor promoted. Just because you don't like it doesn't make it biased.
Having a Noble only area, isn't biased. They aren't picking a select few people to bestow great treasures upon. They would be making a dungeon that players who put in time, effort, and devotion to playing the game a reasonable perk. Something that anyone can do with proper time and effort.
