I think many people run the front too soft and the back too hard. yes this will mess up the geo.
your spring provides support and sets the sag, in the case of pikes it is an air spring so it will ramp up as the fork compresses, the volume reduces and the pressure rises.
all air springs have this behavior and all you can do with tokens is adjusts how fast this ramp up takes place.
softer(lower rate spring) is not really better to keep your suspension tracking over bumps, and harder (higher rate) is not better to stop pedal bob or reduce rider induced changes.though it may seem to help it is wrong.
it is the job of the damper to provide controll to the movement of the suspension both in high and low speed events and the job of the spring to provide the correct level of support for the rider and bike, not to stopp dive or absorb energy from the trail.
of course there is plenty of rider preference and trail conditions to consider plus I have hugely simplified all of this and may be completely wrong 🙂
