This grammar hurts my brain.
: You see Wukong, when you build
, your attack speed BECOMES the damage.
: ...Master, I don't think that's how it works .__.
: I don't see the problem with his logic.
Why don't they do what they did with
to these problem causing assassins?
As I recall they said in their patch notes...
"Stop me if you’ve heard this one before: a high-damage carry champion builds primarily tank items and still manages to deal enough damage to duel everyone while being impossible to take down."
Hmmm... I think this applies to more than just Fiora...

I propose that all assassins have good base damage at level one. However, upon leveling the skill, the base damage hardly moves, maybe going up about 20 per point at most. This would prevent tanky builds . Their ratios could then be high, as items would be necessary to keep their damage.
If they need damage, it needs to be primarily in their scaling. If they wanna be tanky, they will have to deal with awful 120 base damage on their good skills, and thusly doing nothing.
That's more accurate than any developer corner could ever be.

Do u even tank bro?
They called me crazy when I said fighters would be back.
They think they can keep the meta out of our grasp for long, they are sorely mistaken.
Our time will come, it's only a matter of time before the people realize we still hold the true power.
And when that day comes, they will truly regret trying to cast us from our rightful thrones!
Meanwhile in a more literal term;
