Arena and Rated BG's aren't really all that different, as both are competitive PvP. 5 man's are just a sandbox for people to gear up. You also didn't respond to my suggestion of a fine alternative to obtaining rep through the BMAH.
I just thought of an existing alternative for you as well: http://www.wowhead.com/npc=50831
If BMAH is an alternative to raiding then this mob is an alternative to dailies.
