The main reason most ppl i try 2 get to play the game for not playing is the enforce roll... because a person shouldn't have 2 submit 2 one role for many in game jobs even in wows case has roles but your not enforced 2 be a tank as warrior that alone turns more ppl towards wow than ffxiv.. now the defense ppl use for the tanks are well you can off tank which is true however 97 percent of the game you are the only tank so not rlly a option outside of a select few things only about 3 percent of the game has 2 tanks and 2 healers
