Critical Strike > Lethality Prove me wrong.

Greetings Everyone!

This will be my 1st post ever! (Aside from my introduction post) And I raise you all a hard question for any champion AD based and that very question is , critical strike vs lethality. Personally i think i critical strike is allot stronger over all compared to lethality since a crit garen can decimate a lethality garen and since a crit yi can destroy a lethality yi. However i understand each champ is unique and some can scale pretty well off lethality compared to critical strike, but on atleast 70% of match ups i think critical strike should over power lethality.Let me know your thoughts and theories.

Kind Regards
