Cry about bruisers all you want but...
Even right after the juggernaut update you would never see a legitimate team comp include up to 3 bruisers at any one time, EVER.
Darius in his prime was still forced into top lane, and was niche at best as a counter to certain melee assassins mid.
Garen sucks balls all the time, he only didnt suck balls when his ult was bugged and did dmg based on his own max hp bar (LUL).
Skarner in his cancer state was still only allowed jungle.
Mordekaiser is pretty much the only juggernaut, no, bruiser, who can be played in at least 3 roles.
And no, you would never see more than 2 juggernauts or bruiser at any one time in a game ever. It was troll, and you'd set yourself up for failure in higher elos/competitive.
Now ADCs on the other hand? We all know what they're capable of when they're too strong like they are now.
