So what's the edge of being melee?

As we all know, Ranged offensives have always been better than melee, and hell, even the military proves that. We don't use swords, we use guns. So what's the advantage of being melee? Precision. It's much harder to miss point blank. Problem? There is no "precision" mechanic in lol. You rightclick, animation goes, =1 =damage. There is no precision outside skillshots. What does this create? It creates an inherent advantage for ranged champions when it comes to offensive powers, and it forces melee damage dealers to posses high amounts of mobility and damage to work, otherwise they're trash. (Ie. mordekaiser. {quoting tastypotatox, challenger morde na}) And even with bot requirements met (Master Yi), the champion still happens to be trash outside bronze-silver. This then forces melee damage dealers to posses utility (Yasuo, wukong) and even there sometimes they're still fucking crap (Aatrox. He has mobility, aoe damage, burst, dps, some cc and yet he's a pretty crap pick). In otherwords, melee damage dealers MUST be able to do literally whatever the fuck ranged carries can but better because they are in dangerous positions for doing ANYTHING. In other words, Yasuo/riven/Wukong/etc are not designs of broken champions, but designs of melee champions that work in modern lol.
