PROS:
● Good escape and mobiliti
● "Unhookable" Use E in good moment to dodge all hooks
● Easy farm with Q
● Fun gampelay (when 40% cdr)
● Attack speed steroid W for teamates passiv for u
● Skill spamer (when u have recommend runes and masteries in early too)
● High range and high dmg AoE Ultimate

CONS:
■ Only one CC (from gaunlet)
■ Difficult to master
■ QWR are skillshots it can be hard but its rly funny when u master it !
■ Squishy but not as much as all ADC (gaunlet gives u aditional armor)
■ Highly focused
■ Needs a lot of Gold

WHY 1% CRIT ?
Hmmm how many times u have situation when ur anemy need 1 auto attack to dead ? And how many times u have situation when ur anemy escape with 1hp ?
Now u know why i pref one lucky crit than 1AD. And one lucky crit can win early trade.

WHY +2.25 FLAT MANA REGEN?
Its simple i like poke my anemys with Q and safe last hit with Q so flat mana regen its rly helpful to spam it. BTW blue Ezreal is mana hungry only in early game

WHY?
-Its simple: Ionian boots - 15%CDR + Reaver 10%CDR + Gauntlet 10%CDR = 35%CDR So u need only 5%CDR to get 40%CDR and u can get it from this masteri.
-I like spam Q so it is rly halpful same as runes :)
MUST HAVE on adc who is skill spamer like blue Ezreal.

WHY MAX Q?
Q is ur basic skill who can short ur cd (works with pasiv) and gives TONES OF DMG

WHY MAX E SECOND?
E can help u to escape or start fight highest lvlE=shorter cd. And E make dmg remember it !

WHY NO ONLY Q+E AT FIRST LVLs?
Cuz when u shot W on ur temate u give Attack Speed Steroid for he and u.

- Basic Spell combination Flash gives u escape when E is on CD or when u dont have mana. Heal is better than barrier cuz gives u movement speed after use and u can heal ur support or other temate who need it.

- Use it when anemy team have support with hard CC or jungler with hard CC like Amumu or Leona.

- Not recommend on blue Ezreal but u can use when u will play agresiv lane.

POSITIONING
U must stay always in safe place out of cc range and all time MOVE dont stay and AA like wood BE ALL TIME ON MOVE AND OUT OF FOCUS
FOCUS
U must focus ADC>APC>Jungler/support/top but u must look all time to be safe so BETTER FOCUS TANK AND DON'T DIE THAN FOCUS APC AND DIE offcorse when u can focus adc and be safe better focus adc or other squishy target who make much dmg.

U are adc so u should have highest farm in team. U should have 80+ cs in first 10 mins but u must look to poke ur anemy and be safe. When u have problems with last hit u can make custom game add one advanced bot and learn how to last hit here.
