Or keep one slider, but affect different units differently (e.g. "2x" will increase trooper conversion by 2, but keeps Juggernaut at 1. "3x" will increase troopers by 3, but Juggernaut by 2).
Honestly though, I'm not sure if it's so much of an issue.
Right now the conversion rate is 1:3 for Battle Forge units, and 1:2 for everything else. Bumping up to 1:5 for Troopers might be what you want, but 1:5 for Warlocks might not be. I think that this debate is academic though, I don't expect sliders, and certainly not 12 sliders.
