Please, call me naive.

I feel that if the developers designed the game with two different classes as tank, then the game can be completed with either class.

I don't see one as "better" then the other. Each has benefits and limitations.

Isn't it for us, the players, to learn the pluses and minuses of the character we are using and develop tactics to exploit the benefits and mitigate the weaknesses?

Isn't that what this is about? Isn't that the point of rolling a character in the first place?

On day one, you make a choice. End game is the consequence of that choice. All classes/jobs/whatever can complete the game, but whether you are successful or not is based on if you learned "how to play the character".

Am I not correct? If so, I don't see the point of this discussion.

Oh and thanks SE for the server fixes! I can now play!

Love,
