I play because I want an experience. Having fun with other people, doing things the game provides for you to do (and some things the game never intended!) Call me casual, but I'd rather fill my hours with messing around the world given to me than waste my time grinding for better gear/stats in the same spot over and over.
Did you ever do an LS-wide naked rank 1 race into dangerous enemy territory? I did. And had a blast!
Did you ever make a Tarutaru train follow you around Jeuno? I did. Choo Choo!
Did you ever randomly power level some guys in Valkurm, because you know their pain? I sure did!
Did you ever go exploring just because you've never been there before? Oh sure.
Did you ever offer free teleport service, just because? All the time.
Did you ever take your significant other out on a "date", visiting pretty places while having a small adventure? I sure did.
Did you ever just happen to chance upon an NM, call your LS mates together, and win the fight to receive a super rare item? I did! ROC STARS FTW.
Look back on the time you've spent playing this and other MMO's. What moments were most memorable? I guarantee it wasn't the hours spent grinding or camping that NM. Why someone would want to play hardcore and compete with other players for the best items is beyond me.
I play for fun. I'd rather the game designers kept that in mind, than solely cater to hardcore content for all you people who seem to forget what gaming is about.
