I recently fought a riven in lane as master yi and won, riven is fucking overpowered as shit

how did i win by 50 health? well, we both had full health and no ignite, i was level 5 and she was level 4. I had a brutalizer and she had dorans blade and long sword. She engaged on me as i sat in THREE ALLIED MINION WAVES, i EVADED HER STUN with my q, kept attacking her, and then BLOCKED HER THIRD Q with my w to reduce it by 50%.

so basically with all those advantages and 3 full waves of minions doing 150-200 damage per second, the riven almost won, thankfully i finished her with a quick double strike that was luckily up.

how is this excusable? and then of course later she wiped the floor with my level 11 yi with ghostblade when she was level 9 with brutalizer even when i dodged her stun again. This champion's dueling is just so incredibly overloaded its insane, her burst is enough to kill your carry five times over and you can't ever catch or escape from her(i was yi with rank 2 ult and ghostblade active with rank 2 boots and her no boots ability spam caught me over the course of 5 seconds).

she needs to be tuned down, right now her damage is frankly insane.
