Of all the fully evolved fire types, ninetales has the lowest attack. That's why it's allowed to get flamethrower earliest. The others either have high attack (rapidash, arcanine, flareon), not so high attack but guaranteed crit slash (charizard), or fire punch (magmar). All of them can be taught fire blast, anyway.
Not everything having immediate access to powerful STAB is fine, and your buddy finally getting the ultimate fire move only after sticking with them until the late game is fun.
