they cant cover EVERY possible idea that every player could come up with ever, thats not reasonable.
no they cant and i dont even ask them to
what i ask for is the changes being dedicated to their recievers
by making rune glaive cinderhulk and other stuff that junglers needed basicaly a free power ... they entered the area where ballancing those items has certain risks to it because jungle demands ... but sating jungler's might push those items onto lanes becuase they are cheaper and offer more
and riot was aware of that ... the thing that i consider bad is not that they cant contain the chaos ... but that they chose not to even try
they implement what they want into this game ... and then just stick a bandaid to the points where the game breaks
instead of simply implementing changes that dont pose such a threat to the game's ballance
