actually i have a question draztal, let us assume for a minute that, the player is casual (read: not alot of time to spend in game but capable), and is able to cap valor points in a given week, yet doesn't have the time to rep grind from doing the ridiculous number of dailies that are currently the main end game focus of mists until we are allowed into all raids and RF is active etc etc, with a total cap of 3k VP available per character (still don't know why this was added and yet CP was left untouched), how then is this type of player supposed to get gear?
When it is tied into gaining at least honoured standing (after a needed and tbh overdue fix), by the time they reach this required reputation, they will highly likely have out geared the rewards, and therefore have nothing to spend VP on, and with no currency conversion MUST spend it in order to gain anymore. I know ppl have been spamming forums wanting the good ol' days of TBC back, but it doesn't work in the current climate of gamers, mainly because the number of us players from back then and earlier are soo few RELATIVE to the number of new-medium term players, players who have no memory/knowledge of the game before wrath/cata, they will say that this is all a pointless waste of time/effort and not bother playing, and as i read in several blue posts on MMO champion the developers don't have enough "resources and time", perhaps they would have a bucket load more time if they weren't trying to ressurect an old style of gameplay that no longer has a place in the current game.
N.B: i don't mind rep grinds nor do i mind having lots of quests to do (don't like dailies but don't mind normal quests), my arguement is from the point of the player that will likely make up a vast portion of the WoW playerbase.
Sounds like a rather edgy case, meaning, if a player is as casual as you described, it'd probably be best for that player to focus on cap his valor through dailies, so that he'll be grinding whichever reputations he wants to focus on at the same time. If he chooses instead to focus on doing heroics until he gets his gear, then after he's done with that part, he might focus on dailies.
The problem is, this case is littered with too many "ifs". For this discussion it'd probably be much more useful to know what's exactly concerning you :-)
Also, keep in mind that Pandaria isn't going to vanish into thin air. As long as you're progressing towards your goal, even if it takes you longer than more dedicated players, isn't that still advancing your character? Just curious.
