I strongly believe mage items now have problems and lack of variety.
First on, I simply adore mages. I like their playstyle their drawbacks and strengths. But, when I play other classes I find that the itemizations are very unflexible. While ADCs have bork, or IE. Toplaners have hydra or cleaver. A normal mage core build is almost locked into place with no flexibility. As saying, its a huge ball of AP on top of AP without unique stats aside from mana regen. The largest culprits are.

Another problem is that there is WAY too much cooldown reduction, that it is now a spamfest on top of spamfests. (Like how the hell leblanc can Q and Q and proc mark around 35% cdr? ) Cooldowns were a large factor of actually exploiting an enemys opening and now it is not much of a thing anymore. Actually there is so much CDR that there can even be a option of a item of REDUCING cdr at this point.
Another thing that needs to be looked at is the hextech items. They were supposed to fill up playstyles and niches. Which was a clever idea. was supposed to be amp item like RFC, ruunans, shiv, PD for adcs. ...the problem was that they were TOO niche. I cant recall anyone buying GLP, gunblade is used to exploit damage coverage rather than sustain. Had to admit protobelt is nice though. This has been said on this board several times, please consider creating hextech items for sheen users, mage assassins, and battle mages.
Edit: I hear a lot of players complaining about mages these days. And I also believe that it is valid. Since the builds offer no actual drawback and it is the best of the best of statballiness snowball. We can change this, you know but a few factors must be changed, tweaked and revised and open up new bridges for variety here.
is only ever considered on champions who normally rush
is only ever bought champions that have hybrid scalings, or have abusable single target spell damage. (and recently, now being used as a pseudo DFG burst proc.
do i feel is actually bought for its sake, but even it is mostly only gotten on AP bruisers and mobile champions like Fizz, Ekko, Ahri and Rumble, Kennen, etc, as most AP champions like Lux, Xertah, Ziggs , Brand, have basically 0 incentive to get it ever.
line, as it would make more sense on that item, and perhaps even make it less unappealing on none dot champions.
is a little dangerous tho. you would have to handle it very carefully or it would end up being an instant rush and staple on every ap champion.
is required and you get to pick 1 item.

and maybe
That's about it.
before they reworked that into a support item and decided mages aren't allowed to have good mana regeneration and must rely on having a deep mana pool if they experience significant mana costs (not really a bad change, also not one that really helps either, though it does make engineering non-abusable component items a bit easier if that pattern is in place). Some mages that don't need CDR and really want some tank stats because they're short range or do damage over time may pick up

treatment, and this would also allow

are actually decently common buys on squishy AD champs. I think having an AP component similar to
that builds into 2-3 different magic pen items would go a LONG way towards solving this problem (note that I think no one item should give more than 15 flat magic pen, no more than 10 from the proposed component, since MR values are usually still lower than armor, and people need armor to tank tower shots/jungle monsters).
: A bundle of stats that everyone wants, that gives you flexibility in how you'll build when you finish it into a complete item. Problem is, it's hard to make such an item, because there's no stat that is the AP equivalent to crit (ie, all carries and only carries want it).

give 40% CDR together and most AD champs can use both items.
