"smoothing out" the lane phase is funny.
ive laned against one, and he kept pushing the shit out of the lane, because he kept clearing creepwaves with blasting smite. i think its a problem, when he can farm like a boss and contineously shoving the creeps into your turret without mana management.
boom, creepwave gone, and then spam q while his opponent desperately tries to freeze the lane and has no creeps to hide behind.
i think its easy to fix. have the aoe of blasting smite not affect lane minions, and only the minion youre smiting directly. would still make it useful to get a cannon minion out of the way, but you cant just walk into lane and instantly clear an entire creepwave.
