Amongst a total of approximately 75 finished items, about 38 give cooldown reduction...
This means about a little over 50% of all the finished items we currently build give cooldown reduction. (not exact numbers, but this number shouldn't get any lower than 40% depending on which items are counted or not)
This, combined with runes lowering cooldown even more, just put the old League to contrast, where CDR was a rare ressource availlable to only some item paths for some champion groups only.
Maybe, just MAYBE that, in a meta where a lot of people complain about ability spamming, high damage and gameplay being way too fast, this MIGHT be a factor that you should look into, Riot. Building CDR should be a choice, not something you get for free along the way for almost anybody.
