Cry more or make a constructive thread instead (but since we already have one, just post your thoughts there ffs). Enough said.

the problem with him on 1vs1 is that he has too much escaping/chasing tools:blink,stealth,fear,slow,illusions (hope he wont be the only illusion champion from lol,phantom lancer was my absoulte favorite DotA hero) so you can choose to kill (try) him fast or frun from him until you die (I played a shaco with 30% cd reduction from nashor's and brewtalizer and a somewhat skilled yi on the other team,he never escaped from me despite using his ult and ghost and he didn't casted them at the same time).the problem with him in teamfights is that he is capable of creating loads of confusion among the enemy team:1.5 secs of fear,an area damage illusion,5 secs of stealth every 6 seconds (riot stuff you must make his stealth to bwgin cooldown after he ends his stealth,i had 5.87 seconds cd on my blink and if you don't count the 5 seconds of stealth it means you have instant stealth every 1 second)
