I don't see what the issue is. Level-grinding is just a time-waster for people to participate in certain fun events. After I took Warrior to 50, I was looking for any way to speed my Dragoon and Monk to 50 too because all I really wanted to do was Primals and other endgame content. It was too fun.

I'm a boss fight fanatic. I just want to get levels fast so i can go have fun battling bosses.
