We need more crit item variety

Currently in league if u want a exactly 100 % crit build u have to always buy infinity edge and essence reaver cuz these r the only items that give 20 % crit . On the other hand there r also melee charecters who want pure crit and ad not attack speed but to get atliest a good % crit chance they have to build a minimum of 1 attack speed items. Furthermore some of the crit items r ranged only like Runans and lets be honest Rapidfire cannon wont be build on a melee champ for that extra 20 range that makes the options for melee champion only 4 meaning if u want 100 % crit u gotta build those 4 specific items every game. In my opinion that borderline destroys the room for creative builds and isnt very healty for the game . A solution would be the addition of more crit items .For example some that give health and crit , ad and crit , resistances and crit , ms and crit and many more . This will allow Champion like Ganplank to not have to Sacrifice either Trinyty or 100 % crit cuz otherwise hell be sure to get 50 % cdr and 2.10 attackspeed when he doesnt rly need that much as or cdr.
