Change Jinx Like This.
Jinx is not too far out of line, but her ability to push turrets at range with a 100% up time aspd steroid is quite unmatched by anything in the game. Add into this the fact that you can't be anywhere near the tower when it goes down or you basically get jumped by her and her team. Seriously, if you go down at level 9 to her and her support? Your tower is gone and chances are they get to kill you again right away if you're almost back to lane when it goes down.
So, to curtail this, I propose a change to Jinx that will not affect her power at all when fighting other players, but will slow her roll on towers.
Q: Switcheroo Pow Pow: Grants 10/15/20/25/30% passive bonus attack speed. Attacks against champions and minions increase Jinx's attack speed by 6.67/13.33/20/26.67/30% for a maximum total of 30/55/80/105/120%. Attacking a tower will maintain stacks, but does not benefit from the stacking attack speed nor will it build new stacks.
So she basically gets her per-level attack speed back that she otherwise loses (puts her at base 2.76%/level while in Pow Pow), but can't just mow a tower down in 2 seconds flat anymore because she gets a 120% bonus attack speed all the time.
In case you're wondering, no it won't be faster to attack something else and then the tower in alternating fashion to keep her aspd high. Sure, she'll get more attacks out per second, but won't push any faster.
I would like to state that Jinx is in fact my favorite character in the entire game, and I'm well aware of all of the QQing that has been going on, this is an attempt to quell that before she gets Urgotted. This is literally a change only to her tower pushing ability, -NOTHING ELSE-
