As the title ask, does 14 create and promote a culture of mediocrity within it? I say it has been sliding that way since ShB. The healing and tanking roles have been reduced to dull, hollow shells of what they were in HW and SB. The skill celling and floor no longer exist for these roles. DPS roles are heading in this direction as well with all the flavor and mechanical complexity being slowly striped away. See the removal of synergy and reduction of positionals, and reduction of punishment for rotational screw ups. These issues, however, are nothing compared to how the community and general attitude have shifted toward shielding the bad from valid criticism, and a general apathy towards self improvement. Even the devs have admitted to designing content in this manner. It's all quite disheartening, given 14 was at in time one of the most mechanically engaging MMOs.
