Rework Draven Passive

I think it's pretty safe to say that Draven has the worst passive out of any champion. Though it can be argued, at the end of the day by the time you're at full build you'd be lucky to thank your passive for 1.5k of that gold. Then the passive is absolutely useless in every way shape and form unless you want to sell items or buy elixers, both of which you can do without the passive. I understand he is a very strong champion, but at the end of the day most adc's can solo him now because that passive just gives nothing. I was thinking that alongside the gold bonus, for every kill the passive could give maybe like 5 AD + 1 AD for every stack consumed. Or 1% crit damage + 1% crit damage for every 25 stacks consumed. If you consumed 24 stacks you get nothing, so there is a way to very powerfully limit him but also give him a slight edge that helps even a little. This can work with any stat but I feel like it should be considered because his passive is so bad right now
