Mercurial Scimitar, Bloodthirster, Infinity Edge, Essence Reaver, Trinity Force... just to name a few items that, off the top of my head, had their AD lowered in pre-season.
Sorry, but you're wrong.
And yet ADCs have more AD in general than they did before. Previously, you generally got two attack speed items. Now, you get one attack speed item because it also has crit. Couple that with CDR being the main stat on marksmen items, and you get marksmen ADCs with a lot more AD and a lot more ability usage than previously. 250AD used to be the norm, now its 300+. Or in the case of zed, 700+. Take into account marksmen abilities are often escapes or very powerful harass tools (Caitlyn W, quinn vault, sivir ult, lucian dash, vayne tumble, corki and ezreal w) they can use those damaging or escaping abilities almost 50% more than they could previously with very little alterations to their build path. Hell, IE, ER, and DD were super popular for awhile for that exact reason.
So...
70 (zhonyas)
100 (ludens)
100 (RoA)
100 (raylais)
120 Rabbadans)
Is 490AP. plus rabbadans 35%, that turns into 662. so about 700AP counting runes.
Before, you had;
120 (zhonyas)
120 (ludens)
120 (RoA)
100 (raylais)
120 (raddadan)
Which is 580AP. plus rabbadans 35% that turns into 783. Over 800 counting runes.
That is an absolutely MASSIVE dropoff considering AP champions have long cooldowns and full damage was more or less a snowball thing. Could replace raylais with the new morellos and be good though, since its 80 AP got buffed to 100.
