Playing an immobile caster when the enemy team has a fed bruisers/tank at top lane is really fun

Please add more items to deal with this bullshit, so the entire advantage provided by winning my lane isn't thrown out as an 8-2 Mundo presses R and right clicks me.

There's way too much MR + health in the game, and this is compounded by how every anti-tank AP item has a fucking terrible build path and is generally not viable until 3rd or 4th item, at which point it's generally too late.
