I'm pretty sure part of the fix was also allowing you to gain .4s and .5s for much longer. Scythe and defensive skills are my only non-blues on WAR. I took a lot of my skills right up to cap with .4s and .5s still once in a while, which was unheard of before the update.

My skillup theory is basically:
[Skillup_Rate, Skillup_range] = fSkillUp(Monster_Level, Your_Level, Current_Skill, Maaaaaybe_Weapon_Rank)

Examples:
Skillup_rate = 5%
Skillup_range = [.1,.2,.4,.5]


In the past, you skilled up to the cap for the monster you were fighting. Now, I think you can skill up to about 5 levels over the monster you're fighting, though I can't say for sure. My THF still gets dagger skillups off T1 VNMs outside Abyssea in Ronfarue, so that would be a good way for me to check this for sure. I Colorful'd though, so we'll have to wait to see what it caps at. =p

Furthermore, I think they adjusted the skillup range so it includes .4 and .5 over a much larger range. I took skills almost all the way to cap on WAR while still seeing .4s and .5s, while pre-patch it they simply didn't happen and .3 was my max.
