i don't think you understand
ezreal in 2010 was the HARDER champion in the game
not only because he had 3 skillshot, but becaue he was a godamn burden of knowledge champs. His W had healing+attack speed buff+ attack speed debuff+damage. That made 4 situations you had to consider to use your W and you could heal yourself by teleporting on your W.
ezreal is my favorite champs, i stopped playing him not because he was boring but because i can't stand having 3 spells as AD ezreal while the other have 4. the only situation where i can use my W is when i E in that's nothing compared to before. i find AP ezreal fun in late game but his early game is boring with no damage. i just hope that riot realise that they removed his attack speed debuff when the problem was the width+ the damage, they nerfed all 3....
