Its not as if they even require any sort of serious time commitment. Lets say you do the GL and Klaxxi dailies to start out. You alternate between the two factions each day, and take every third day off. If you completed the quests in The Dread Wastes to unlock all the Klaxxi dailies, then you are already honored with them. Revered will take, at most, 13 sets of dailies. While you are doing that, GL dailies start off at friendly because of the intro quests. Do the GL dailies that are available and you will reach honored after 5 sets at most. Then another hub opens up so you are getting more rep per set. Honored to Revered with GL takes 8 sets of dailies max. Total of 13 sets of dailies, approximately the same as the Klaxxi (Crazy its like Blizzard planned it that way or something). Doing this on the schedule I mentioned earlier, you have unlocked all the gear available from 2 of the 4 valor factions in a little more than a month of VERY casual work on the dailies. And in that time, assuming you valor cap every week, you have the potential to earn 6000 valor, which is less than the cost of available pieces on those 2 vendors. You could space it out even more and it would not matter. Because of the caps in place you will not be able to earn valor faster than you could unlock gear to purchase.
Dailies are the required activity to access this gear. Just like raiding is the required activity to access raid-dropped gear, and dungeons are required to access dungeon dropped gear. WoW has worked this way since it launched. The only reason people complain now is because suddenly there is a reward that they want access to that requires them to do something they don't want to do.
