Ezreal Build Guide by d1JJRiE
Not Updated For Current Season
Really i would rather go with barrier since ezreal already has his e for an escape.
So he can escape/absorb more dmg if needed. \(._.)/
Build in order i would try to go with the trinity force first. then stack 1 or 2 doran blades to help with the dmg/hp steal. i go with the black clever to help with the whole team since it reduces instead of penetrates.
Natural runes, id rather go with the Armour pen marks then ad, either way it helps early game.
