Bloodrazor and lifesteal
I think Bloodrazor passive should applies lifesteal and have 10% lifesteal against all target instead of against jungle only.
It scales very bad late game, that should help.
My 2cents.
EDIT : Comment below
My feeling is that you're forced to build tank with this item as current, since it's scale of nothing you can buy (except armor pen but meh.) Some buy this + Botrk to have some lifesteal, but then with shoes included you got very to only AS, to render your build worth you must go tanky to apply your DPS a longer while.
Another problem with bortk+Bloodrazor is that it's 90% AS, + 2 on-hit effect, to make this build worth you either go Strength of the ages or Fervor of Battle, both don't scale with anything you'll buy too.
In case of Fervor of battle, you'll get 3 on-hit who don't depends (or nearly don't, the on-hit of bortk is healthier) of your stats.
Fervor could use of some AD scaling (like 2.5% bonus AD per stack to a maximum of 20%) and less base damage.
