Placeholder aside what would be wrong with 4pc being 5% to Wrath/Starfire in t7 and 5% starfire only in t9.
Im sure with all the other stats you are gaining from going t7-> t9 losing 5% crit with wrath vs adding 1.18% total chance to crit (before gems) (5.22% crit rating on t9.5 5.14 on t7.5 520 int t9.5 333 int 7.5 giving you 1.1% from in <187 diff) and .08 from crit rating, incase you wanted to know my math). Not to mention the difference in spellpower you will have with t9.5 vs t7.5.
Perhaps they figured, with the bonuses already being allocated, that giving the same bonus as 7.5 would not be as balanced, especially with the eclipse buff they have given us.
Try it on the PTRs if you get the chance. Wear 4pc t7.5 vs 4pc t9.5 and see which has an overall superior dps, mix up the rotations as well to get the full effect, I for one am curious to see the results ^_^
