So basically you want it be more carebear....

Not everyone wants MMO's to have an easy progression... While fights can get me angry, I'm still enjoying it, and it will bring a lot of joy when you finally beat it.

One of my favorite games outside of MMO's, is Dark Souls. That game was very challenging when you first went through the game. The boss fights in it, where a lot like you described FFXIV Primal fights to be... You mess up once, and you have to do it all over again (and usually a lot content before the boss too).

Dark Souls would've sucked if it was easier, and the same goes for FFXIV.
