I'm still waiting for your youtube video of you going to the beach and calling girls derogatory comments because they wear swimsuits.

Solo is ok, but that's not why you should be playing an MMORPG, solo MMOs get boring and stale quick, why do you think people are sick and tired of "The same old MMO"? Every one is solo centric then you live in boring instances for the rest of your career.

How do people do a quest if they can't heal themselves without an overpowered easy mage class that almost has unlimited healing..
Get some friends or LS mates?

Or make cure 2 cost 50 mp so we can use it at least 8 times..
Nope. It's perfect the way it is now.

I am someone that wants to go his own way in a game
There's plenty of MMOs out there where you can do this now, FFXIV may just not be for you -- They're redesigning this game and like it or not, there's a lot more people who like doing things in a group setting than lonewolf. There's going to be lesser content for soloers, especially after further adjustments, but do not expect this game to be another MMORPG where you can solo from start to finish in everything, they may as well shut down FFXIV for good if they go that route.
