[Star Wars] What would've happened if Darth Vader hadn't gotten burned?

Say he only lost his arm, and I guess both of his legs.  But he never caught fire, and thus, never needed a respirator.  How would things have been different?

Being less robotic would have made him able to access the force better- a creature of mostly metal is going to have trouble accessing the power of life. The Emperor would have then considered him a much better choice for future Sith Lord, and by the time the Rebellion started up he would be able to crush it before it snowballs out of control.
