I dont think any of the AP assassins are actually that bad

It just feels like all the new or changed items .. counter them too well along with the items that already countered them and especially / still feels way too broken against them and AD assassins can still build it no problem. Like, you go 0/2 in lane against an ap champ? Just build Hexdrinker/Maw and youre back lol.

And apart from that, tanks got better tools now (especially the new keystone), AD assassins got new items with more utility and damage tools, ranged champs in general got new masteries to abuse while AP assassins got... An Abyssal nerf, a Revolver nerf and a Protobelt nerf.
