If you are using Roland's Aid station skill as a campfire it is not necessary to have 5 ranks in it. If you do the, its 20 seconds of 5% regin which is 100% over the 20 seconds, but most people will not be down to 0, because you can't be.

If your using it during battle it might be worth it though.

Also, an example of a skill that doesn't need full ranks is Roland's Guided missile skill.
