Yep, the disparity between the stat change across ilvl vs the max stats reasonably available w/ 5 materia is noticeably larger now than in 2.X.
Also the value of secondary stats has gone down by ~66% across the board, which again severely reduces the value of the max available melds.
Granted this is for DoW/DoM classes, the stat increases were not nearly as high for DoH/DoL... Just reinforces the idea that the devs want High End Adventuring and High End Crafting/Gathering to be very separate things.
