The only legitimate complaint you've even brought up in this thread is the loot lockouts, literally everything else you whine about is either a problem with your attitude or not even a problem to begin with.
1.) You don't like the dungeon.
Good for you, don't do it.
2.) People are rude because they tell you what to do in the dungeon.
Zomg how dare people try to make a dungeon run somewhat organized, they should let you learn at your own pace and wipe 23 other people 50 times.
3.) The dungeon should have been in the game at launch.
Yes, it should have. SE stated it was supposed to be. It was always meant to be in the game from launch onwards. SE had to postpone adding it because they had severely overtuned the mechanics making it nearly impossible to clear without full i90 (which you may recognize as absurd for a dungeon that drops i80 gear).
