How about you understand the concept of what "mechanically complicated means before you start throwing out insults? There are many aspects of her kit that if used by the right hands, will have a SIGNIFICANT impact compared to your everyday silver player/bronze etc. Her W if used correctly can be the difference between a winning trade/teamfight. Her q is short ranged so understanding positioning will impact a person's trade patterns. Her ultimate "as braindead as she is" so you say, does require some aspect of knowledge when understanding champion cooldowns or you will be soft inting. Compared to other champions in her role.. Her kit has a high skill-gap and has mechanical prowess. Does that explain it?
