Can we please see some GP nerfs soon?

Between having to ban Nasus and GP (because of klepto), I always have to leave one open and far too often gp gets played. I mean you ca just check his playrate right now and you'll see quite clearly that he's extremely popular for a top laner and extremely broken too. All these mastery 7 GP "mains" coming out of the woodwork isn't a coincidence, especially since his playrate has doubled since the preseason.

If it were up to me id make his w have a flat mana cost at 120, and have his q scale up from 25/30/35/40/45 instead of having his q stay constant 40 and his w scale. The point of his w having a high mana cost is so he cant spam it in lane for free heals all the time but he does that anyway because its his only real mana cost.

Other changes that couldbe nice would be: Having his q not do bonus damage to champions at range, Having his w heal scale with level, having his barrels not slow for 80% at any point in the game, Having his passive grant a flat movespeed boost or a sclaing one instead of a 30% boost (alternativly nerf his moespeed by 10 to 335), and have hise cost mana to use (20/15/10/5/0 with rank or something along those lines). (Not all of these maybe one or two).

I'm very sick of seeing GP in my games because of how uninteractive he is and id prefer if he wasn't strong without meaningful forms of counterplay.
