There are too many anti assassin items

Title.

For how team fight oriented this season is Assassins are already at a disadvantage. Isolated targets are extremely rare, pretty much non-existent. To top that off, there is Stop watch, Ninja Tabi(still too strong on ranged champs), GA, Zhonyas, Deaths Dance, Phantom Dancer, Exhaust, Locket, all of which are mainstream standard items built in almost every respective AD/AP/Support build.

There is nothing assassins can do. Tuning wise they are fine, the issue is overloaded defensive items that aren't even defensive items. Theyre hyper offensive hyper defensive items jampacked into 1 purchase(with the except of the support items).

Deaths dance needs a mitigation nerf. PD needs to have mitigation or death defiance, not both. Ninja Tabi needs to be halved for ranged champs. Stop watch needs to not exist. Zhonyas needs less armor. GA should have a melee version and a ranged version. 70AD+ressurection(Pickaxe instead of chain armor) for ranged.

Until the game pace changes and there is such a thing as isolated targets.
