Yes, if you want fully proportional independent steering you'll need two 
PWMs, but the 8-way control provided by the relays is usually sufficient 
to operate effectively on the battlefield.  Throw in proportional speed 
for each of those 8 directions and you've probably got more than enough 
control to do anything you want on the battlefield.

Keep in mind, when you're being attacked by overwhelming numbers, the 
difference between a fully proportional arc, a partially proportional 
arc, and a high-speed spin is academic ... adrenaline overrides fine 
motor control :-)
