How to Update Melee Basic Attackers
I love the idea of Yi and Tryndamere, but the truth is that they are either utterly useless or completely oppressive. And they do it in such a way that they aren't even the least bit fun to play against.
But if we take the lessons of two successful carries (Fiora and Yasuo), we can see that melee basic attackers can be done well if given the appropriate means of interactively dealing with Marksmen.
What do I propose? A new type of unique item passive and an item for it:
Cestus of Defiance: low-med attack speed, med-high base AD increase (to prevent assassins from abusing)
Unique Passive - Furor (as old boot enchant, potentially stacking with phage)
Unique Passive - Close Quarters (melee only): 20% reduced damage from ranged basic attacks for 2 seconds after striking a champion with a melee basic attack. Casting a spell ends this effect
An item like this will enable champions like Yi and Tryndamere to sustain a fight without having their kit tuned so high that they can't be beaten without drafting a team specifically to stop them. Their power can be nerfed a little on its own knowing that they can pick up an item that plays off their strengths. But I hesitate to propose defensive stats for it so Marksmen don't just buy it for the stat line.
It can also be made to function off crits rather than any melee basic attack. Either way, it emphasizes the fantasy of a master brawler being tough to shoot from range while he's cracking skulls on your frontline
