Change IBG for Ranged Champions. Something needs to be done about Ezreal Permaslowing Everyone.
A Max Range Q into a clumped team, or a team following the same path all have to endure the slow field that remains after an IBG Spellblade proc. IBG Spellblade should be a single-target slow for Ranged Auto-Attacks and On-Hit Effect applicators (i.e. Ezreal Q). This would allow for ranged On-Hit applicators from melee champions (i.e. Poppy Passive, GP Q, etc) to sill be considered Melee Basic Attacks and still apply the Slow Field from IBG.
There's no reason why Ranged Q spam should be able to slow a whole team and negate any chase. Right now you either have to instagib the Ezreal, or disengage before he can start permaslowing everyone.
