Quick simple suggestion that really should be implimented.
When a player makes a bio that is overcap on resists they obviously are set to the 75 cap. Sometimes you get a bio that say has two stats that are under the 75 cap mark, but the rest are in the 90s. What I suggest is allowing the resists to equal out the undercap resist stats so all resists under or over the cap are set to 75.
I suggest this because after a bio get capped, all the points of resists are just *poof* gone, why not allow the lower resists to be capped with the extra points?
Well then every poorly made bio pet could be modified into a max pet...

Resists, yes. Stats, skills, base dmg, no.

The reason I brought this up was from making a bio that had 3 resists in the 90s and two of them were at 73. When the bio's overcapped resists got set to 75, the bio still has 2 resists that are 73. For an extra 4 points of resists the bio could of been made to have its resists standard, at all 75.
Surprisingly enough people don't want a bio that does not have all resists at 75. Unlike the majority of other pets that can be trained/bred to improve stats/skills/resists, bios are the only one shot creation pets. Bios are also the slowest attacking, which is why resists become such a large factor in determining if the bio is worth anything.

Blight, seems like a reasonable suggestion to me. I do want to point out to those unaware, you can use the pet repair system to boost resists up to 75, even on bios.
