For many Sims is a tool for their storytelling, so the option of disability wouldn't be a mistake. The attitude towards disability displayed in this forum is bad enough for EA to consider this move as to raise awareness. We have different walking animations, having a wheelchair animation wouldn't hurt anyone. Using mental illness as a gameplay gimmick would be not taking the issue seriously, but in a world with disabled Barbies there's also a market for a disability/health expansion pack. Add flus, accidents with broken bones, anything lightheartedness. Comparing disabilities to dosmetic abuse is quite honestly insulting.
