To start off, I want to note that this is not a rant, but merely a suggestion and some theory craft.
Critical strike is the only thing in this game that still has the "luck" factor. It can't be controlled and is therefor a random event entirely. So basically anyone getting killed by critical shots, is getting killed by "luck".
In my opinion this should change. Make that Critical "Chance" an actual Critical "Calculation". What I mean by this is;
- Instead of rolling a dice every attack whether or not an attack will critical strike, make every Xth attack critical strike based of your critical strike chance.
So if you have 10% Critical Strike Chance, make every 10th auto attack strike for the damage by default. I would go even further, give it a separate "critical strike counter" with a visual effect, much like Caitlyn's Headshot.
This would result in a reliable and visual poke that you can actually use to get the advantage on your opponent, or backfire on you if you don't have the awareness to deal with it. It will prevent overshooting on some minions you AA as well, which I know you shouldn't anyway, but I'm Silver and main support/tank, sue me.
It will also create a "sweet spot" for certain champions and their skill sets. As mentioned Caitlyn's Headshot would have this spot on her seventh attack. So about 14-ish percent would be perfect for her. For a champion like Vayne you'd want it to be at once every third attack so that it stacks with Vayne's Silver Bolts.
Now for all this buffing (which it essentially is) you'd need to reduce the actual Critical Damage and it's numbers, seeing as how bruisers could build an Atma's Impaler and a Trinity Force to critical strike every 4th attack for 200% of their damage (excluding runes). So that would be a balance issue. And Ashe would need a new passive, but she needs to be reworked anyway (yes I really think Ashe is broken).
So, as to my surprise a lot of people are actually pretty satisfied with the way Critical Strike works now. Some agree with me that there's a change needed, just not in the way that I suggested, while the minority likes my idea. The "raging" was kept to a minimum, which is nice.
