Limited rewards can be viewed as a reward in itself from SE for dedicated customers/fan base who maintain a constant consistent monthly subscription that is able and also motivated to partake in these limited time event/reward offerings. Putting a window on it only makes the rewards that much sweeter. I do miss FFXI's rare/exclusive items that really were special and unique snowflakes.

It took me a year to get my black belt waist armor for monk, and when I got it, it was and to this day the most rewarding thing I have done in an mmo. I'll never forget that moment, and it will always be immortal in my heart till the day I die. Just kinda wish this game had something comparable with lasting staying power.
