I think pretty much everything that needs to be said has been said in this thread;
Daily quests aren't mandatory, there are alternative means of obtaining gear outside of them, that being heroic dungeons, pvp and raids.
The coins were meant to be a bonus for raiders so they have another reason to log in every week aside from the scheduled raids, they serve this purpose well and do not need to be changed. They are far from mandatory considering the really low chance of you even getting a piece of loot from the boss, and even if you do it might be something you already have or otherwise don't need.
Daily quests are fine, if you don't like them then do what you do with other content you don't like, avoid it.
