Re: Why not to shift?
Added complexity. Servo-based shifting is slow and somewhat unreliable. Pneumatic shifting is much better, but if you have no other pneumatics on your robot the compressor is going to be a giant power suck. It's also easy to pick the wrong gear ratios and end up with a low ratio that's too low and a high ratio that's too high.
There's also the issue of training your drivers to use it properly.
Ideally, pick a gear used only for pushing and climbing (mounting the bridge, etc.) and another for regular driving.

Everyone builds their robots uniquely, runs their teams differently, and prefers all kinds of flavors of ice cream. Now, we are seeing that folks vent and react differently to a frustrating situation. ... and that's ok. - Andy Baker [more]
