S10 Conqueror is bad
Welcome,
Season 10 has started off probably worse than any other season. New conqueror is a joke. All you do is stack armor and what is 15% of 0 damage? 0. Don't tell me to build black cleaver because that item does not even come close to closing the gap. All new conqueror is good for is either fighting other bruisers, or good on mages. If you're a bruiser fighting a tank, you might as well give up because once they get Sunfire Cape you no longer have an effective means to fight them. Sunfire is 200g cheaper than Black Cleaver, that's almost another cloth armor by the time someone gets their Black Cleaver, then they just stack armor.
