lol... seriously?
The basic thing to know is that if you can clear 16 floors, you will reach floor 100 13% of the time. 17 floors gets you there 30% of the time. If you're not horrible at this game, 16-17 floor average is pretty easy to accomplish, which means you'll be getting at least 1 win a week. How long has nyzul been out now? 4 months? whats that like 17 weeks? Looks to me like if you were using all your tags on nyzul with a competent group you'd already be 15/15.
Also: If you can clear 18 floors, you'll be on 100 52% of the time, 19 floors pushes it to 72%. Based on how good your group is at Nyzul directly impacts your ability to reach 100. Based on this you can see that very good groups will be able to finish much faster than average groups. Saying anyone with the gear is obviously a cheater just shows how misinformed about the event you are, and maybe even how bad at FFXI you are. Have you even gotten your friends together and done a few runs and seen what your average floor clears will amount to?
