There is something missing for control mages

Control mages really fell out of meta for quite some time now. I'm talking about Lissandra, Heimerdinger, Taliyah, Anivia, even Azir and a few more. This is not just because most of these are really weak now, but also because there is no good itemisation for them. Most control mages became burst mages, because there are not many ways to build for an AP. The usual core builds are items like But most of these items are rather good on burst mages.

What is a control mage? Control mages have a rather slow early game. They are defensive, their laning phase is not too strong and they do not have too high damage, but have lots of utility. Taliyah and Lissandra are prime examples for that. You could debate how Taliyah has much damage when she hits her entire combo. That's true, but it is the result of riot forming her from a control mage into a burst mage and the itemisation. I really love playing Taliyah and I have adapted to her playstyle past patch 6.14, but honestly, she was so much more fun back in the day. It is not much fun playing her as burst mage, when so many other champions do the job much better, and it is really tilting. Lissandra has been really popular some time ago, but all riot does is changing numbers of champions, instead of nerfing too strong items and bring in more choices for items. There should be more items with AP and Armor/HP/Magic resist. Items for control mages should have a rather low amount of ap, but bring in utility and defensive stats.
