Riot a improvement that would actually help Irelia more then the current PBE buffs would be...
Making the cast speed on Equilibrium Strike faster.
It says it has a cast range of 425 but it takes what seems to be at least half a second before the effects happen.
It is extremely noticeable when playing against the likes of Singed and Volibear who will always be able to fling even when getting stunned.
Not asking for damage just for Equilibrium Strike to be more responsive.
