Crit Chance is a problem.
I think the thing that is currently breaking the game is the RNG of Crits. For me Crit is the strongest type of damage of this game.
I know that Riot is making a change in the way of correcting this issue with the "marksman update". And they should keep on balancing RNG maximum and minimum values.
In my opinion the way riot is going with next patch will not solve the issue. They will delay the powerspikes and crit based ADC's, making sure they dont come "online" in the game as early as "RAW" AD champions.
But, thats it... After the ADCs get the items they need, it will all be the same... or is there something more that i'm not seeing it?
