Completely removed damage from Shaco?

I main Shaco as a jungler, and before the assassin update I was looking forwards to the clown getting some love with a rework. Seeing updates to champs like Talon and Katarina, I expected the best. He was already strong while he had obvious downfalls, and I wanted to see him get some reworks. However, after the update, I've noticed a trend of doing nearly no damage. His Q Auto Attack doesnt do bonus damage but instead a flat damage. Backstab crits dont seem to count as actual criticals either. I've noticed that when hitting lane minions, my random chance criticals actually do MORE damage than backstab, indicating my Infinity Edge didn't apply crit damage to backstab? It became redundant to even try to backstab when I did more damage just by auto attacking. Even with his recommended build, taking duskblade and black cleaver, this massive damage reduction makes him die before he can even burst down most adc's now. His Q damage caps out at about 800 with full build, and without the ability to actually crit through backstab, IE becomes an almost useless item. Not to mention he is still revealed by items like Oracle's, despite his abilities clearly stating only Turrets should be able to reveal him. Overall the new rework to Shaco removed his ability to be relevant to a fight until well after the fight is near over. Not to mention his 3 ult boxes have near no health, and when one dies they all die. I have yet to see someone actually get caught up in his triangle of boxes.
