Ezreal makes games stale
In tournies he's one of the most, if not, the most picked ADC. Why? Extremely safe, punishing if you slip up and take a Q (especially if you have gauntlet) and hard to stick to/assassinate as they just rush icebourne gauntlet into tabis usually.
I find this patches pro play games extremely boring to watch due to it. No actual fights happen, just poke poke poke. Saw saw a game that ended 9-1 (team wipe at the end) due to this. Ezreal only died because he didn't build a null magic mantel against a leblacn with 30 magic Pen in items that she rushed (bought more offensive items despite her being the only threat).
I just find it silly having to dodge 1000 Q's against an ezreal in lane (very fun) when he never runs out of mana after 1st/2nd back.
Making gauntlet a melee only item would be a great start so that it can be used to stick to slippery champions for melees, as ranged doesn't have that issue and it only makes them oppressive.
