Every Week, you'd have to do it like 4 times (per alt) to maximise point gains.
I think a ToC esque instance would complement a tier nicely. Something like OS or Magtheridon where it's meant to be a short, sweet instance, and not the heart of a tier.
If they pushed a ToC esque raid alongside a 8-12-boss full-on raid, I would not complain. (as long as it was one lockout a week, of course.)
EDIT: poll: Faction Champs 10m was pretty awesome. I enjoy actually getting to use a lot of utility to win a boss instead of relying on tank and spank.
