What are your thoughts on a 4 player content similar to savage/extreme?

I think it would be nice to have other difficult content that isn't just 8 man.

Things i would like to see
Savage Dungeon
Extreme Trial
Savage Raid

Doesnt need to be alot, maybe just 1 of each released the same time the regular savage/extreme content is released (even patches, odd patches, etc)

This would be nice for smaller FC's, easier to work around 4 peoples schedules for statics instead of 8 people.

Im not sure what the rewards could be, obviously not the same rewards in the current 8 man content.
