Why I Think Giving %Crit Cance Some Static Percentage Damage Would Spice Things Up
i was listening to WingsofDeath yesterday and he was talking about how he'd go for that 1v1 between him as lucian vs graves but didn't want to chance it over who gets the first crit off. I think adding %crit would make the game more fun. you'd see more duels and #LCSBigPlays. less risk = more reason to fight/less reason not to fight. Also, by adding percentage damage you could use the new +crit %dmg runes. and could still farm creeps with %crit chance runes. Builds like shiv + ghostblade could work. or triforce phantom dancer could work. or IE triforce (since you'd have enough % crit chance runes to give you say 40% chance to crit). apart from equipping maybe 1 or 2 crit marks crit runes are hardly used unless you're gp/trynd/yasuo. Early game phase will be cooler bot lane since you'll have more crits early game.
Say you have 100 damage and 25% critical rate, means that every 1 in 4 attacks should crit, but that does not mean they necessarily will. With in the attacks, all 4 could crit or none could, which would be the extremes. Ideally though, if 1 attack in the 4 crits, then you would deal 500 damage, due to one of the attacks damage being double and without factoring in armour and the like(100+100+100+200=500). Percentage Damage instead spreads the ideal damage over those 4 attacks. So, if you have 100 damage, each of your attacks will do 125 damage, so you would deal 500 damage as well(125+125+125+125=500).
i think the solution would be to draw from both. reach middle ground/split the difference. give every auto attack increase dmg based on % critical damage, but only 50% strong, while keeping actual crits in the game just make the actual crits 50% less strong. you can still crit it just wont be thaaat big itll still be noticeable. more like a sheen proc than a trinity force proc. so in your example Percentage Damage instead spreads the ideal damage over those 4 attacks. So, if you have 100 damage, at 25% crit chance each of your attacks will do 125 damage.
Solution: take a bit from both worlds Such that you would do 112.5 damage per auto and have a chance of doing 112.5 + (100% of dmg x 0.5) so essentially adding half your damage to that. so 112.5 plus 50 = 162.5. so the new max crit would differ by 200-162.5 = 37.5 dmg. from the traditional/current crit
