CDR As a Stat Becoming Irrelevant
I've noticed something that's been happening recently. Everyone gets 40% CDR (or 30%). Everyone. It used to be a decision that had to be made: do I want to buy more damage, or do I want to spam my abilities? Now CDR is on most of the items that are core to builds. The possibilities are almost endless.

This isn't an exhaustive list, just what comes to mind. Most of these items did not used to have CDR as a stat until recently. This change has caused balance issues (such as the recent dominance of champions like Orianna, Fizz, and Syndra in the midlane). These champions had ults that were on a long enough cooldown that it was necessary to use the ult strategically. Now with 40% CDR (without sacrificing a full-AP build), these champions can use their ults with impunity. Was this change intentional? If so, why not just remove CDR as a stat and focus instead on balancing skill cooldowns? It seems that by saturating items with CDR, it removes a dimension from the complexity of building a champion correctly (and in a way, the associated diverse playstyles).

. The defensive path often has CDR for sustained damage, while the damage path is very glass cannon.
