Welcome to the world of ezreal top!
Why play ezreal top?
First off ranged top laners are great counters to things like sett darius and most op melee top laners! If you do end up facing like a kennen teemo vayne top lane, don't fear because you can just farm with your q while rushing cdr and if they try to hard engage you have a built in flash in your kit (your e)! Secondly, imagine an adc who gets an insane mid game power spike, and they get solo exp and solo farm!

Pros!

1.Super Safe! With his short cooldown and range of his q you can safely farm, and with his e you have a free flash!

2. Great teamfighting

3. Great kite cause there are alot of kiteable toplane meta champs right now

4. Really strong mid game that scales decently into lategame

5. You can, if need be, go for some ap if their whole team is stacking armor!

Cons

1. Squishy

2. Bad damage early game compared to other adcs in the top lane like kalista and vayne

3. You will most likely (in low elo) already have your teammates tilted by you choosing ezreal top in the first place. :P

4. You will most likely lose early game! LOL

Ezreal's early game in the top lane is a coin toss. You either a cheesy early kill or you lose lane and come back mid game because his mid game power spike is great!

80 percent of the time you will lose the early game because well its ezreal top but feel free to give up a tower for not dying cause if you can farm safely and scale you will be insane in teamfights!

You also wanna try to help out your team with TP and your Global Ult! (for cheesy kills that tilt the enemy i have gotten so many kills with cheesy ezreal ults)

JUST PLAY SAFE AND DON'T DIE if you get the opportunity try to make a play kiting...

ANYWAY! LONG STORY SHORT SCALE FOR MID GAME GET TO A TEAM FIGHT CARRY THE TEAMFIGHT WI GAME! :P

Look for fights to Tp to, group up cause mid game ezreal in fights is really strong.
Play safe in teamfights dishing out damage if you die or get caught out before a teamfight, and then your team losing the teamfight losing the game or you die fast because of bad positioning or bad use of flash and e and throw the team fight. if you lose, it is probably your fault! LOL

Split push and stay around objectives be ready to tp or ult at a moments notice dont get caught try to not fall off keep up with your farm!
