Please look at wondrous tail rewards.
There's no real reason why you have to make getting two or three lines in it such a low percentage. The only worthwhile rewards are the gathering/crafting VI materia tokens and five slot gathering/crafting body. Tier VI combat materia is worthless, the level 60 ornate crafting is pretty worthless for the low chance of getting it, and the 320 combat gear is for one job at a time, and is obsolete for anyone except people who were into progression.
The best reward in tier 0 is a dragonskin map I can gather in 5 seconds.
It's starting to feel less like "here's some stuff for helping others by doing things!" and more like "why are you wasting time?"
