Here's my two cents.

The rankings are too Marvel orientated for my liking. Why can't I get to be a "Guardian of the Universe" or a "Controller" or even a "Monitor"?
It's just not fair I say.

I like it!

This may be documented here somewhere but I read the first page and then skipped to the end...Is posting the only thing you get points for? Thanks

Here are some other ways to earn points:

Submitting Change Requests. The number of points varies by the type of request.

Voting on change requests - You get one point after the CR is approved (I'm not sure if you get anything if it's rejected, also if the CR is modified, the votes clear)

There may be other ways, I'm not sure.
