Speed is what it is and any change in its dominance would probably break Reddit. I may be the only one who enjoyed the way mods were on release. At least then you could load someone up with an obscene amount of protection which could absorb the extra turns gained from speed. But even statistically speed outpaces all other skills as a percentage of base stat.
Frankly gameplay would probably have been better without secondary skills and just primary and mod sets but that wouldn’t drive spend in the same way as the slot machine pull of secondary rolling.
