Coins are not required for bosses at all, so the people who only raid, yet want the coins, should be okay with getting them other ways. I do agree that it needs to come from more than just the dailies, and as I said before, i think this is just a test before they start spreading them to other areas such as a profession tied system, or maybe to stuff like Darkmoon Fair, or different other things, but the simple matter is, Blizzard wants people doing more than just one single thing, and the coins are used to promote that period. If you feel forced to do dailies even though you don't like them, just so you can spend a coin and get 28g, that is for you to decide, but in reality no one is forcing you (well except maybe your guild, and if that is the case there are always other guilds). Coins don't make someone more or less competitive, coins in general just provide with a low chance of getting that one piece you might be missing, and even than, if the boss drops more than on item you could potentially use, the coin is even more of a gamble.
