Is anyone else starting to think IE is an extremely unhealthy item?
I suddenly realized this. Think about it--so many complaints about champs and their crits are mostly because of this item, when you get to the root.
"Yasuo does way too much damage"
pretty much nullifies the crit balancing.
"Jhin literally 1-shot me" --2.5x damage 4th shot. Cancels out reduced crit damage.
"Cait's Headshot+Crit dealt 1000+ damage"--she wouldn't without the crit amp.
(haven't seen this as much anymore but still) "Vayne literally 1 and/or 2 shot me with a crit" ...You get it by now.
It also increases damage output that applies Lifesteal too, which gives a ton of (potential)In-combat sustain that no one bothers to build
or
against, indirectly making lifesteal stronger on champs that build both.
Infinity Edge is very much contributing to the complaints regarding crit damage(well, damage in general), but the champs are blamed more in spite of the crit amplifier being the root.
etc. all feel unbeatable when far ahead enough when fed if they have lifesteal and at least 50% crit
If IE gave something besides the 2.5% crit damage, all of those above complaints would be addressed in one swoop. This is just guessing since I haven't thought about what effect it could give, but maybe some sort of Ramp-up like guinsoo's for ADC and Attack speed+AD champs? I'm not sure what it could give besides an amp, but it's a guess so far, and champs could be balanced around not having that.
EDIT: perhaps a solution to make it stay the same late game would be to make the crit damage amp scale with level(thanks Erockandroll), to hopefully prevent more abuse cases from happening so several champs don't get nerfed instead.
I know it's been around for a long time, but there has to be some better way it can be in the game so there wouldn't be such high damage crits. People are complaining about damage creep, and this would lower ADC's damage across the board, with weaker champs being addressed individually.
, don't tell him, you'll break his heart.
change i have to rely on
and 


etc.
from the game because it only builds into Zeal. Make the recipe for Zeal
+
and give the crit to Zeal as part of the combine, like how all Cooldown Reduction items work.
