But how is it fair that she can just clear waves an spam all her stuff as most of her "counters" drain themselves of mana. Allowing her to just continue to spam without losing anything from it.
How would it be fair then that Riven has 0 ranged attack to poke with, huh? I guess you think that would be fair when you play the right click hero from a distance and kill her without any chance to get damaged because she has to you use all of her mana for her shield and dashes just to avoid your right clicking skills and ranged aoe cc. Yes, that would be fair, balanced and skill-based totally. Also the easiest champion to kill is a Riven who just spams her abilities because if she does that she leaves herself wide open for damage while she is the squishiest toplaner in the game. Her Q has 13s cd which does not scale. Moreover, it is always funny to read when someone is complaining about manaless champions while most of the mages has low mana cost, thousands of mana and ridiculously high mana regeneration at once. Riven has to worry more about her non-scaling Q's cd than mages have to about their mana.
