Burst items could stand to lose some AD and gain some HP/resistances.

So that they can never be broken again, unless they're just completely overloaded with stats and then it'll be blatantly obvious to anyone at that point, let alone Riot. There, someone said it.

Duskblade deserves to lose a large chunk of its AD and really could use some armor. Assassins wouldn't mind having access to it beyond Tabis and GA, as well as anyone else looking to build lethality.

Stormrazor definitely deserves to lose a large chunk of its AD and equally deserves to have to include HP. That way marksmen won't rush it literally every single game like they do now as they don't care for HP nearly as much as others. Also, it'll fit nicely on HP items and champions that like building HP.

Buying both items would then encourage assassins to be assertive and to use their survivability in fights, rather than go all-in on one-shotting squishies in all aspects of their lives. In other words, they'd be interactive for once. Rito, pls.
