@Riot: Do you actually like where crits are at the moment? Are you thinking on changing them at all?
(This is not a complaint topic. This is asking Riot if they are looking at other crit topics at all.)
As many people have said, Critical Hits are one of the last major RNG elements in gameplay that have a major impact on games. One lucky/unlucky crit can decide many a team fight, something people hate having to leave to luck (even if your chance to crit increases with each non-crit).
People have suggested ideas such as "remove crit chance and change it to simply increase the damage of your basic attacks by X%" or similar stuff, with varying levels of complexity. But I'm not here to suggest such a system.
I am here to ask you whether or not you are even giving any thought to reworking/removing/replacing crits. Is it something worth doing, or would it not be worth the immense effort?
