I am exalted with most factions on pandaria and I will have to do dailies just for coins.
Before a blue comes saying coins/dailies/valor are not required: they are. If you are doing any kind of progress the chance for extra loot (or being able to get valor gear) is really important.
If I had listened to gms saying "dailies and valor are not required" I would have been without gear to enter my raid team since I had bad luck on lfr/sha/rolls.
if it isn't clear coins= elder/lesser charms of good fortune
