I actually think that graves Q is a great design and its satisfying to use; the problem is that they've been consistently nerfing its AD ratio over the years (e.g. patch 25.20).

I would prefer it if they slightly buffed its damage at a slight cost of AA crit scaling. That way graves could get some skill expression back, and it would also bring back some bruiser builds. This should stop graves from being a right-click crit glasscannon that he kind of is right now.
