The fact remains that you can freely play any job you want with 110 gear, 115 weapon, and 115 accs (1 for each primal during the current phase. Currently just shiva) with unrestricted farming on anything in the game except 3 fights (which was still done with extreme skill). It IS a multi job game. 3 fights you have to specialize or just be rediculous awesome. Don't change the while system because you can't go to t13 on your 5th job 2 weeks into the patch.

There's nothing to fix.
