I find this to be just a slight buff to his AS Steroid, which that's what it is. Overall he's going to be slightly better when dishing out damage. Riot's trying to show that yes, Ezreal is a skillshot spell-slinging marksman but he does good damage with auto attacks. They're buffing that so Ezreal is slightly more noticeable when it comes to being a standard ADC and he has what it takes to bring that to the table.

Trinity Force will probably be seen a little more, he's going to be slightly stronger than before especially for those that favor a TF + BOTRK build rather than Iceborn.

I can't argue against this, I'm too lazy to go through again and update the rest of it. I agree this isn't a great guide. I focus on builds because that's what most people look for in the first place, but that's no excuse for the lack of explanations everywhere else. I apologize.

The build section is pillared and sorted wrong, and some items are out of date, im too lazy to try and fix it.
I say essence reaver isnt that good right now, it would apply to more crit yet mana hungry champions like Ashe.

And for the Black Cleaver thing, i realized that both bork and last whisper upgrades (especially when paired together) are really good and cost efficient, where as black cleaver is still pretty good, i dont think it provides as much since the last whisper changes. It's still a good item if you want to be tankier, lets say your build would be bers greaves, manamune, black cleaver, iceborn, then two other items probably revolving situationally around bork, last whisper, and mercurial, you'll have a lot more survivability and stats that are perfect for Ezreal. The only problem is that it takes a really long time to build up your items and you dont do much damage, it's almost inevitable that you lose most of your early game until 30 minutes.

Took this in to consideration and I realized that Cleaver was indeed better. Thanks for your suggestion!
