I couldn't agree more here. I got my 4-set at the end of this reset. My overall item level hasn't gone up; I just now have 4-set and expect to do much better on damage than I did last week as a direct result. I did also sneak Thok's Tail Tip which may help too
Which reminds me; I also dislike the huge power trinkets now have. I miss the days when they dropped a toy cannon or some voodoo gnomes. I understand that WoW is a gear driven game and of course output should increase with level of gear. However, the quantum leaps in output that go with getting the specific items (which may have been sidegrades when considered on their own) can be a bit deflating for those that take longer to get those pieces (I think myself lucky I have the 4-set, a normal warforged weapon and all the useful trinkets within the first month).
