So something that goes along with the length of the campaign is also the idea of how you could make each campaign unique. Something I would like to see is a secondary skill tree that is eared quickly and resets itself each campaign. Nothing of course that's really powerful is earned in this tree, but it does add an extra layer of customization that can be changed every campaign, allowing and even encouraging players to continue to mix up their bag of tricks.

How I'd imagine it to work in a week long campaign:

Earn you maximum amount of points in about 30 mins. Resets at the end of the week.

Two week campaign:

Earn half of your points in about an hour over the first week. At the beginning of the second week, everyone, including those who have never played can re-select their first 1/2 of their perks and begin to accrue new ones, maxing out in about another hour of play.

More than two weeks:

Really starts to get hard to accommodate everyone. I'd probably just keep trying to build on the two week system.

I like where your head is at, but I would tie the points to your factions completed objectives for each campaign then have those points be used for things like titles and decorations that would change from campaign to campaign. Rather than a time limit (which could be easily abused) I would have participation metrics used; X damage done, bases capped, etc.

As an example: in the first campaign your faction completed enough objectives to earn 500 points. Your participation metric for that week was enough to get you 50% of the maximum so you have 250 points to spend on a new title and a cool decoration for your strike cruiser. Your friend played hard this week so he earned 80% of the maximum possible, he has 400 points to spend of this weeks selection.

Great idea.

I also feel we should stay away from giving out extra skills/variety, even if it unlocks in <2 hrs. For most people, that would just become an annoying "have to play for 2 hrs to get my skills back, yawn".

Turning the concept into a reward that links to titles and other bits and pieces AND encourages sticking with a single faction and pursuing its objectives...like I said, great idea. Provided there aren't too many unique bits per campaign, as that would annoy the completionists and stress out someone on dev side who has to churn out (x) new content every week. Or it would require campaigns with longer time frames...which would be no bad thing either.
