Riot, why are you endorsing crit?
Seriously, you put AD ratios down and crit chances up. Not to say more crit chance is bad, because it makes the game less centered around chance, but that's exactly what crit is. Take for example a few games I had today. First game I was Yasuo, and got Brawler's Gloves after first back for 20% crit. I hit a crit almost every time I AA'd or Q'd with only a few exceptions. So that was a 1/5 chance to hit a crit every time and I hit it more than 2/3 of the time. Later, I played a game as Tryndamere. I was doing wolves early and had full fury by about the middle, but never hit a crit. Went into lane, didn't hit a crit until I got early ganked by Evelynn and died. Came back with Brawler's Gloves so I had 45% crit at full fury. Only hit a crit maybe 1/10 of the time, which would be good... if I didn't have my passive crit. But I did and even with enough crit to almost fairly hit a crit every two autos, I almost never hit it.
Mobas are based on skill and strategy. Crit is based on chance. Crit does not belong. Remove it.
