Actually, the thing that bugs me most about the variant encumbrance rules is that, like the regular encumbrance rules, they are still linear. I don't think a Str 30 monster is supposed to be merely 3x as strong as a regular human; and I don't think a regular human is supposed to be merely 3x as strong as a cripple or 10x as strong as a rat. (x5 for Strength 10 vs. 2, x2 for being Medium vs. Tiny, total x10.)
I grew up on AD&D, so I naturally think carrying capacity needs to be more exponential in Strength. Either that, or Str needs to not be capped at 30.
