I was thinking about creating as a playable race these genetically modified humans that, instead of gaining a feat and skill increase, gain +2 to an ability of their choice and darkvision (with no penalty to an ability and no LA; i realize that not all ability scores are equal but when you have a certain build you know what ability is most important to that build, so while STR and CON are, in general, some of the most important abilities as a wizard INT is WAY more important to me than STR or CON; these humans give the PC the ability to pick their ability MOD). I was looking through the standard races for comparison and saw that the half-orc gets +2 to STR darkvision and a penalty to TWO abilities. That would give my genetically modified humans better racial MODS than one of the standard races; however, it doesnt seem like these genetically modified humans have that great of MODS. Do you guys think these humans are "too good?"
