User blog comment:TheTobarMethod/Ezreal Mid Anyone?/@comment-128.230.201.184-20130119054200

I don't mid as him because:

1) He cannot waveclear without using his ult. If you can't waveclear, you can't push the lane to roam, and if you can't roam, you can't apply pressure and snowball yourself or assist other lanes.

2) He has absolutely no utility. He plays entirely seflishly, provides no crowd control effects, and can do little more than mediocre single-target damage.

3) Ezreal has no lane control. Since he can't waveclear, the enemy mid lane can simply ignore/dodge his harass and push him to his tower. Ezreal farms poorly under tower and cannot clear the waves fast enough to not have the tower take significant damage and farm while he's attempting this. Meanwhile, the enemy mid lane has already left to gank other lanes and your team is angry that you have no control over you lane.

4) If you're building AP, then you're going to need a significant number of items to put out any from of relevant damage. If you're building AD, then you're wasting the mid lane even more. AD carries don't need levels, they need gold, so you're essentially wasting the lane's experience on a champ that provides little payout. If you're building hybrid, you're useless until you sink 9k into items, give up and start builing AD again.
