Ideas to nerf graves without gutting him

So, it seems fairly clear that graves is slightly too strong. However, he's a tough one to outright nerf without making him bad or even useless. therefore, i've thought about two ways that probably wouldn't make him too weak, but not the powerhouse he currently is. Of course, i don't mean to neccecarily apply both of these at once.

1: Reduce the first pellet damage by 15% (60-95%), but increase each additional bullet by 2% (27-38.6%). This is a nerf mostly targeted at his early game when he doesnt have the crit, but be the same with a normal crit and slightly more with IE. This does, however, force graves to be up in their faces at all time to deal his proper damage, which might be a levearge to control his balance more.

2: Hit his resistances from true grit a bit early game (from 10 / 15 / 20 / 25 / 30 to maybe 8/13.5/19/24.5/30) This is mostly to make his early game juuuust a tad weaker, and allow assassins and such to better kill him before he kills them.

this might just be rambling that noone agrees with, but... what do you think?
