Taking this feedback into account, we're considering an additional mechanic that we think might address both of these issues, without losing the concept of competition that is at the heart of Powerplay (and rightly so in our opinion).
The mechanic would measure the average productivity of each power against every other power at the end of a cycle. This is not the same as how well or poorly the power did, simply how much time and effort its supporters poured into it, as a group.
The power with the most productive average supporter would, for the following cycle, relax the rating 3 requirement, allowing all of its supporters to purchase the power's module.
The next two most productive powers would relax the rating 3 requirement, allowing supporters of rating 2 to also purchase the module for that cycle.
