Zhonya's Hourglass: Give and Take
Many people are complaining about the new zhonyas change, and, lets face it, there is validity behind some of the hate. The lowered stats aren't as effective in dealing with high ad threats, and the increased cool down doesn't help those who are buying it specifically for the active. I understand that its cheaper which is a plus for those with kits that synergize well with it, but the stat drawbacks make it a tough buy for those who want armor and AP but aren't getting it for the active.
I suggest that another AP/armor item be created with slightly increased stats and cost, but without an active. There should be a give and take when buying items in that when purchasing an item with an active you give up stats but in return you gain utility.

(Forgot to mention that the Zhonya's cool down would be reverted with the implementing of a new AP/armor item so those buying Zhonya's for the active would benefit from it, but would make the purchase understanding that the active is what made the item viable.)
