More Flexible Buildpaths for Mages

I'm of the idea that mages need a lot of love these days, especially immobile mages such as Zyra, Brand or Malzahar . Not only are these severely harmed by the mobility creep, but mages in general seem to have a lot less flexibility in what to build than say Juggernauts, Junglers or Tanks do. While I won't say that we don't have our share of interesting and unique options, we certainly lack a consistent ability to capitalize on our own strengths.

An example would be mages who specialize in pushing, although these naturally possess good wave clear and lane control, I tend to find them lacking in the department of actually taking down turrets. Compared to champions such as Zed or Yasuo who often push just as hard but possess the immense advantage of having their primary stat being Attack Damage, which naturally increases their ability to destroy turrets.

I think you should bring back Rite of Ruin to Summoner's Rift, with appropriate tweaks of course, to even the playing field. I'm aware that on pushing mages this item would be extremely powerful, but that's more or less the point, whenever a Zed leaves me behind to gank another lane I should be able to ruthlessly punish him for that by building accordingly. Aside from simply AAing the turret for laughably little damage compared to what he would do to mine were our positions reversed.

In regards to the mobility creep I think Netherstride Grimoire could even the playing field there as well, it's passive is powerful, but has counterplay potential. It'd do wonders to make immobile mages more viable overall, just a thought.

I don't know much about Pox Arcana but it too would've done great at empowering mages and giving them more flexible build paths overall. Even if you don't bring these items back, I'd love to see mages receive some love in regards to itemization.
