Melee champions simply need more bulls**t than ranged to be effective.
There's a very simple reason why champion bans are VERY heavily weighted against melee champions.
Being melee is a huge disadvantage, and because of that the bulls**t in their kits needs to be stronger to compensate.
You know what, A melee champion with enough BS in their kit to remain a threat late game is the best definition of a Juggernaut I've heard so far.
