Gold cost will be like 3250
I think this is too low.
Let's take the most similar item to Dagger of Shame and compare the two.
Mercurial Scimitar.
Both give the same amount of AD.
Both give the same amount of Magic Resistance.
Mercurial Scimitar gives 10% lifesteal whilst Dagger of Shame gives 15% cooldown reduction.
Mercurial Scimitar only has one unique and that's it's active.
You already know what the active does.
HOWEVER, Dagger of Shame get's TWO unique things.
One is free Tenacity and Slow Resistance.
And the other is removing cc from the enemy champion completely, which is probably double as effective as Mercurial Scimitar's active.
And yet, Mercurial Scimitar costs 350 more gold?
Either, Mercurial Scimitar needs to have it's cost massively reduced, or Dagger of Shame needs to cost more.
I mean there is a 5% cdr on 
Yeah but
builds into something that gives 10% (
) so it flats out.
This doesn't build into anything, and thus you'll evantually overcap on CDR if you go for 40%
Those items don't do enough to be honest
CC is one of the only counterplay we have to assassins.
25% Tenacity/Slow Resistance already feels like a bitch when you're up against a fed assassin so giving them even more it becomes a nightmare to actually kill an assassin.
unflinching isn't for assassins
Hey.
That's your opinion, mister, not a fact.
You can't come in here and demand an item that gives you free Tenacity/Slow Resistance, and then when someone proposes a solution to your problem you go "Duh I can't do that because lol"
Besides, you can always take Chrysalis with it.
That way, you're not missing out on that much damage.
Getting CC chained is fun isn't it?
Fighting a fed assassin that can't be cced is fun, isn't it?
Remember when tanks were super strong? Now make them useless
Yeah. You used the word yourself. WERE super strong. They're in a really hard spot right now. With the true damage from Conqueror and true damage from Infinity Edge (everyone gets true damage nowadays), tanks are really struggling to stay relevant.
Let's not give them a harder time.
One QSS vs 10 cc effects
You see how broken your idea is?
Completely negating one cc effect is already really strong, and you want to remove not twice, not thrice, but TEN TIMES the amount?
You're a mad man.
