they are finally learning that ezreal should be built muramana, elder lizard, IBG, ionian and last whipser
I mean whats the point of using ezreal if you're not going to build him like that? Triforce having only 10% crit and crappy slow destroys his S2 build. There was never any point in building him as an ADC when there are better ADC picks at AD carrying. So finally they have adjusted to a S3 build for ezreal instead of trying to play him like a regular ADC by learning from the koreans
The build is Spirit of the elder lizard (very cost efficient and health/mana regen) Iceborn gauntlet (reliable slow, mana, and armor that allows you to win bot) muramana (very cost efficient and lots of mana) last whisper (necessary armor pen) ionian boots of lucidity (CDR for more spells) Blade of the ruined king (lifesteal)
The idea of the build is that you can never die in a team fight or 1v1. Poke people all day and get objectives fast
It's a double edge sword. You give up a lot of team fight/overall damage, for good 1v1/chasing damage UNLESS you're actually able to consistently land you Q, which most Ezreal players can't seem to do.
