Well all these points to serious problems with design of the game, the system, the governing body.
All these instances where healers dont even need to heal. All these instances where you cant get the loot you need without throwing in months of work. All these functions that are just a time waster. All these instances you cant even get a party for. A policy that allows unacceptable behaviour and promotes the undesirable.

You need to make the devs do something about it.

Oh, have you guys tried the player search in the social menus. If you pull it up you will see a long long list of bots.
