A problem with hybrid builds is that you cannot compete output with pure AD builds. That extra 200 AP and 150 less AD? Well sure it improves your ability damage much more, but in comparison, you have much lower damage versus crit-build ezreals. You can get all the best hybrid items you have (Gunblade, Guinsoo, Lich Bane) and you still won't beat an Ezreal with Bloothirster, Last Whisper, Infinity Edge, Phantom Dancer/Statikk Shiv as he'll do an average of 900 damage per autoattack, with his attack speed at 1.3-1.7 per second. An Ezreal with pure AD will still have a very damaging ultimate and a much more painful Q than a hybrid Ezreal.

Regardless of hybrid or AD ezreal, after throwing everything, the only remaining thing you can do is autoattacking, and this is where hybrid ezreal pales in comparison to ad ezreal. Considering hybrid does a bit more damage than AD when casting spells and AD being much more superior after throwing everything, AD is generally better.
