AP Itemization (bit of a rant)

IMO there are 4 AP items right now that make the game so shit to play as a champ without access to these so ill go ahead and list them and explain the problems with them. : Unlike GA which re-spawns you whether it is beneficial or useless with usually not enough resources to continue the fight, Zonyas lets you decide if you want to be temporarily invincible with a lower cool down. Furthermore when you get back into the fight you have all the hp and mana that you have entering stasis. And this only costs 100 more gold than

: Unlike which is only built by Ezreal, almost any mage can build this to get almost infinite mana, decent AP for the value (only a bit less for the unstacked Archangels) , and most importantly a shield 600 strength shield which compared to only the damage from Muramura is a bit excessive.

: Turns mages into tanky champs while also giving really good AP for what its worth. Even if this is not that overpowered, I believe AD champ should also get an item which Scales up tankiness, hp and AD.

: Magic Penetration Item: 40% for cheaper than any of the shitty MR items in the game.

It would be fine if these where some items specific to certain champs that make them work (like Ezreal) any mage builds 2-4 of these items and becomes tankier than most champs (that arent direct tanks) while still giving off damage comparable to any other champ and scaling from an early game which isnt all to weak. You get veigar with his veigar damage 3k HP a 600 strength shield to top it off and zonyas if he gets focused so hard that the 3.6k hp could get bursted off. You get both Ryze and Cassio building all 4 and being some of the most OP champs for a couple of patches now. Kai Sa building Zonyas became the most OP adc in the game for a good time. Honestly just remove these items or have ADC`s run around with 3.6k hp and a decent anti-assasin item.
