Points and ranking pretty much equate the same thing... Your ranking is based on your points in relation to the other players...

Personally I'd say it's based both on points and on which day of the event it is. Some of the bigger bosses are not released immediately (for example, I don't think Twinstrike appeared before day 2 or 3 of the event, even for the highest-ranked players).

Also, level 5 Hun-Gurr... are you sure? I'm sitting at rank ~250 and haven't seen higher than level 2 so far (at least, that's what I was getting earlier today, it's possible they've released higher levels of him just now).
