More content is always good but

1) what loot or other reward do you expect there?
2) gear progression has been like: farm dungeons -> do the raid/ex-primal stuff
3) what gear should be required for those? If you need top level gear for those, the only reward you can give are titles and such
4) will there be enough players doing this, considering the above things about loot and reward vs. gear you need? How many players do savage right now?
5) I'd rather see more full party content.
6) What you want could also be achieved by tightening the iLevel synch on current and future dungeons.
