@Riot Sparkles - What Have You Done 2 Improve AP Champions?
3 Magic Pen Options

3 Defensive Items

Hardly Built Anymore

Build First Every Time

=================
AP mages suffer from a bland itemization, only three defensive and magic pen options, and items that are completely useless and not worth buying anymore. The only comment you have is you are adding ONE new item that is probably going to be another useless Hextech item that does nothing to improve AP itemization.
Tanks are incredibly hard to kill as a mage now. To even do damage we need to build the three magic pen options. AP itemization has been suffering for years now and your mage class update didn't address a single thing, meanwhile ADC, AD, and Tanks get all these options and changes. What have you done this entire time to address these issue? Ignore the community. Do you want mages to be nerfed and irrelevant? It seems that way the past few years. I mean honestly, it has been the ADC show for years now and you even allowed the ADC meta to continue beyond its rework.
Changing the build path of specific items and creating ONE new item is not going to solve the apparent problems this community have been telling you for years. We need more magic pen options, we need more defensive items with AP attached to it, we need more love for AP bruisers/assassins, and just more options. The new item is going to be nothing but another Hextech item that lunges someone forward. CONGRATS! That solved the problem that AP itemization is bland and lacks options.
In reality AP champions need 4 to 5 new items or massive reworks to existing items to make them even relevant now. Adding a Needlessly Large Rod to a build path is not solving a darn thing.
