What Happened to CDR?

Remember the days when you actually had to decide if you wanted CDR, and if so build for it? Now it just feels like something that is built in, and it is more of a challenge trying to not pass CDR cap on almost every champion.

I believe their reasoning likely falls into one or more of these categories:

1. They want to make "easier" build paths (warhammer, codex) and since the new item paths they choose have CDR in them they have to throw it into the final item.

2. They don't know how to trim power on items in other ways, so they just minus some AP/AD and throw CDR on there to try and compensate.

3. They want to eliminate CDR as something people build towards and make it something that is just acquired naturally through item purchases.

4. They simply don't know what they are doing.

With the introduction of the new rune that converts excess CDR into AD/AP, it feels like they are just avoiding the fact that it might be an issue that it is so easy to obtain so much CDR, and instead of making changes so that it is an actual thought process they are throwing in a rune that allows even less thinking about the CDR cap.

Perhaps it is my stubbornness for change but I really miss building towards CDR on some champs and wish it could go back to being less items containing CDR, even if it means more CDR on each of said items.
