Ap vs Ad

It might just be me, but Ad seems to be significantly stronger than ap. On most teams, it is 80% ad and 20% ap, as having more ap would be unwise, considering the amount of Mr items (for ap, ad, and tanks), and the overall lack of magic penetration items (only 3 unless you count abyssal mask or wits end). Compared to Ad, which has more opportunities to spread their damage (AA's and abilities) and their larger amount of lethality and penetration (6 different items), It is simply unwise to have more than 1 ap carry/damage dealer.

Yes, I do know that every champion has scaling armor, but everyone also has scaling Ad, whereas melees have scaling MR but nobody has scaling ap.

At least from my perspective, there is almost no reason why someone should pick an ap champion aside from CC. One thing that the majority of AD champions lack is a lot of cc, so that is why you would pick Tammy supports or toplaners to fill that role. Ap assassins and Mages seem a bit out of the meta now imo. You could say that ap champions also bring high burst (most mages, as well as ap assassins), but ad Fighters as well as assassins can do that just as well.

Lastly, with the addition of the MR item that counters tank killer mages, It really has crippled AP champions. Bring back the ap please <3.
