gameplay bug with aatrox Q

the description on aatrox Q says that he can be knocked back by displacement spells, but he can be knocked back to original spot by any spell, and seemingly even by basic attacks. also he can be attacked by basic atks while mid air in Q. so if your trying to jump onto an adc with 2.5 atk speed u will be getting hit twice during the jump. I have also been trying to flee from adc by jumping over walls and have been killed by basic atks while over the wall, just not touched down yet. its annoying to get knocked out of air by a basic atk and then still have to wait 12 seconds to use the skill again... altho these basics that knock me out or air may have had some kind of skill associated with them (double damage shot after roll etc) which made them act as a skill instead of basic.
