Far enough man! i can see you really put in a lot of time in this guide, keep it up :D

Hi, and Thank you for your kind words!
yes, blade did get a nerf but I still find it relevant for being a tankbuster and overall good item because 6% of current health on hit and 25 flat ad is very strong - for example, against a target with 3k health, an auto attack at this level of health would do an additional 205 damage which is more physical damage than any other item in the game has on it as a base. when they are at 2k health it will be 145 additional damage - and at around 1k it will be an additional 85 damage which is when it's damage will start to fall off and BT will be stronger. And, if the target you are fighting is not a tank and has less than 1k health - they can be easily finished off by your base damage. The thing that I find even better than just having good damage is the fact that Mystic shot can apply this passive from a safe distance, making it do a lot more damage on top of iceborn passive and muramana active.
There's nothing that can really replace botrk since nothing can match it's damage output on most targets + being coupled with 40% attacks speed, lifesteal, and a strong active - but if you want a lifesteal option that works for Ezreal and provides some utility or defensive stats then BT or Mercurial Scimitar are great options - both having the highest flat AD over all other items.

I mainly included Sterak's because it can save your life against champs that can jump into the backline to assassinate you (leblanc/kass), while also giving a lot of health and % base AD increase which will scale throughout any time in the game. Maw can be a great choice if you find yourself in a situation where you're constantly being poked by magic damage champions. I just considered maw to be an item focused towards melee champions more since, if it's being built as a final item, you're probably at the stage in the game where being caught out means certain death,regardless of having maw or not which can't protect you from CC. And, only melee champions who are in the frontline doing sustained damage will get more use out of the shield and bonus attack speed and lifesteal it gives after lifeline triggers.
But it doesn't mean it's not capable of having an impact in your game and does have good stats that are worth considering - I just felt like it wouldn't be a go to item for mid to late game and would rather just have scimitar, banshee's or guardian angel if i wanted something to save my life/protect me from hard CC.

Hey man! guides looking great! good build and the chapters make a lot of sense, however something i found interesting was the fact that you run blade of the ruined king on ezreal, when season 6 had quite the nerf onto it, I find maybe essence reaver is a good choice but it doesn't take advantage of much crit, it does give some good damage and CDR which would help with the poking, without the trinity force it really doesnt have much effect, so instead of that what would be another choice for a 6th item ? i assume having both yoummus and blood on the build instead of blade of the ruined king would work though , since you get a speed boost equivalent to the slow from bortk, you get penetration equal to bortk's dmg per hp and you get lifesteal, however the cost is a bit more, keep up the great work man! keep updating this guide because it has a lot of potential! also maybe insteasd of sterak's maw of the malmortius? idk i've just never seen an ADC build it
