It's easier to do 1 Expert Roulette per day for 6 out of 7 days than to plug away at it endlessly trying to hurry up and get a full suit of Creation gear.

That's what I like about the 450 cap; it is so easy to get, and it keeps these tryhards from getting Full Creation on Day 2-3 while everybody else is still trying to build up for their body piece which gives me some breathing room and actual time to do things other than FFXIV, or things inside of FFXIV other than spamming roulette.
