Now that on-hit bruisers like 
etc are pretty weak, why don't we give them an offensive option that grants utility ?
Something like 
, when 5 stacks are applied the target is bashed aka stunned.
This mechanic is broken in Dota already - getting permastunned is far from fair,
non of those guys are weak, and they each have extreme chase mechanics built into their kits already, add a braum passive to each of them and what you're describing is a game breaker. Then imagine other bruisers picking up the item, you would never escape a volibear again. There's already on hit speed buffs, an On hit stun would become OP and abused by all character types, even if you limit it to only melee, master Yi and Yasuo would abuse the F**K out of it
High attack speed champ or the one with a way to reset autoattack time will abuse it . They changed skirmisher to dot for this reason ( and it were only raw damage ) , stun is way more stronger :P
Some champions are designed with the understanding that they will have zero access to strong crowd control, and so their damage, CDs, resource costs, and other aspects of their abilities are allowed to be superior in that absence.
The addition of item-based hard CC would fundamentally alter such assumptions, and require rebalancing numerous champs unless the item itself were to be so underpowered that it became effectively irrelevant.
yes lets give champs like darius and trundle an itemization to provide them with cc and get rid of their weakness, that would be great. While we're at it let's give fizz/leblanc/zed a stun item to help them out with their combo.
Bruisers are the weakest class in the game.
I'm even seeing Wukongs, Jarvans and Pantheons go full tank. Yes, low utility bruisers that should build damage, are now building full tank. Not even Warrior then full tank, just straight full tank.
Tbh for me it doesn't seem like a bad idea in general, as long as the stun debuff is not permanent sitting on the target waiting to be stacked.
But I wouldn't say the on-hit bruisers are weak atm though.
we do have an on hit stun, the golem's buffs, udyr's bear stun
