Correct me if I'm wrong here, but it seems Season 3 just changed how we calculate the relative worth of Cooldown Reduction.

With Kindlegem, 10% CDR used to cost 322g. (This is based on the following math: from Ruby Crystal, we can calculate that 180 Health=475 Gold. If you divide Kindlegem's health by that of RC, then you can get a ratio for the inflation. 200 Health/180 Health= 1.1... so multiplying 475g by 1.1 would give one the cost of Kindlegem's health, 527.7g. Subtract this from Kindlegem's base price of 850, and you are left with 322.3 gold, or 322 for simplicity's sake.)

Season 3 just changed this calculation with the changes to Fiendish Codex. Judging from Amplifying Tome, 20 AP costs 435g, making the 30 AP found in Fiendish Codex worth about 652g using the above calculations. Now subtract that from Fiendish Codex's price of 820, and suddenly 10% CDR is worth a mere 168 gold. Talk about a steep price drop.

Am I doing the math right here, everyone? Are we going to have to redo the cost efficiency lists for CDR items now? Thoughts in general?
