Could we just try to make EITHER Lifesteal or Crit melee only for just one patch?

{quoted}

I am pretty sure it would balance ADCs ALOT!

It would make them garbage. Taking crits from ADCs in particular would make them laughable. No one would play them.

That would just put adc's at a extreme underpowered state, not balanced at all.

Then push Yi, Trynd, Jax over the edge, no thanks

I mean that wouldn't change much of anything except make those items never be bought by anyone. ADCs would just go the even more degenerate route of lethality builds or go on hit builds. So all this would accomplish is switch which ADCs are good and which are terrible

No way, Tanks will never die if ADCs can't crit.
