15 ammo would be enaugh if you consider that the poison also deals 726 damage to an average 2200 max hp target, and the smoke deals 600.
Yeah, yeah, I know, I was just thinking that she'd be the only champion that cannot under most circumstances rely on her primary fire alone to get a kill. If she always must use at least one of her abilities to kill a target (obviously I'm ignoring reloading, I'm basing the argument on the fact that having to reload mid-fight would always put her at a disadvantage) then she'd become completely dependant on her cooldowns, which I don't think is really a positive change. Let's agree on 17 ammo, this way she'd be able to deal enough damage at least when landing all shots at her effective range.
I think 450 smoke damage wouldn't be worthy to waste it for, she would rather use it as she did it originally: put it under herself.
Well, yes, but if it's too high then the ability primary purpose would become that of being thrown away to damage enemies instead of being an actual ninja-vanish-poof-bomb. It would become a different ability, damage with a stealth bonus instead of stealth with a damage bonus.
I think andro has even worse fallout without Cursed Revolver.
If I'm not mistaken, Andro deals 520 below 50 units down to 208 at 440 units, while Skye deals 130 below 40 units down to 39 at 200 units. With some very rough math, I'd say Andro has a lower falloff (60% compared to Skye's 70%) over a greater distance (390 units compared to 160)
