Reason 1) The game is a police state

read that post, pretty good example of "it's our sand box, screw you". Guess people don't like that attitude too much.
Reason 2) Corruption, hacks, and exploits.
-Listsold hack, The hack that helped many known high tier players get ahead. Get free T11 items by listsending them to yourself, yippie!
(some will say it's a rumor)
-Broken released content that gets exploited. As an example, broken T11-T13 mobs that get raided because of a glitched found or vendors that buy easy dropped items for 10k+ gold(Well that was an easy charm!)
GM and Dev corruption
-Do you have a GM or Dev in your guild? If you don't you might want to consider adding one. Everyone in the "in" crowd knows that they used to respawn and move mobs during raids, adjust damage, adjust resists, ect. Justified by saying "it's not working at intended". "We're testing the new content". Guess what, guilds trying to the same content without a GM Doesn't get that luxury, So yea, unfair advantage. You would think if they are testing the content in such a form they wouldn't be allowed to keep the loot
Once their guild is done with the content they go one step further and "buff" the content. Well it's too easy now that we are done with it.
That's my best guess man.
