Aurelion sol's Q

I know the damage doesnt scale with distance, but looking at the video's of people playing aurelion sol sending his Q from fountain to fountain, I feel like the area of effect could be used too potently to finish off a game.

Say its a close game, suddenly one of the teams sieges the inhibitor turret, 4 of the team mates stay near the turret and aurelion sol backs to base then follows his Q down the mid lane. Instantly the enemy team is faced with a dilemma, do they stay near the turret, suffer the 2 second stun and hope they can fight back with a tower OR do they let it go, only to have aurelion sol do the same thing to their nexus turrets. While this isnt as much of a problem bot or top lanes(even though I can see it being a problem too.) The fact the galaxy has such a large hit box by the time it reaches there means they need to be behind their nexus turrets to avoid the lash back of the ability.

There needs to be an inhibitor to this, have its growth exponentially slow as it moves or a max cap to its size. or entirely remove the stun from it,ect... because this is about the same level, if not more so, then azir's soldiers being able to target turrets, and the problems that came from that

To those who say this takes time to set up, usually an inhibitor turret dance can easily last long enough for him to do this maneuver, and if they are pushed back then it just means aurelion sol has not quire as large but still hugely problematic stun radius that he is dropping on his enemies.

Think of this now before release so we have less "OMG BROKEN CHAMP GG" to worry about when you actually release him
