Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
Having global coverage with Trueshot Barrage can help secure kills, and also has very low cooldown times.
THIS GUIDE IS A WORK IN PROGRESS
Pros / Cons
I go with AP glyphs, because all of your abilities scale off of AP and this helps with early damage output. AD quints help with last hitting early, but can be replaced with AS quints for late game damage output. Hybrid pen marks help Ezreal deal more damage with all of his abilities, and more damage is always better. Armor seals are to survive during early lane phase.
