It's supposed to be like that. Warframes get more exp because you are using at all times meaning every second every kill you get also gets transfered to the warframe.

Think of the warframe as a weapon you have on but is always in use. unlike you're primary, it has to be used when killing to gain exp. So if you switch to your pistol your pistol gains exp for that kill/affinity. while your primary doesnt. I think affinity affects all weapons though so when you pick it up all your weapons and warframe gains 100 exp. hope that cleared you up?
