By that same token placing ANY restriction on the amount you can do will make people feel forced to get the most out of it while they still can because once the day or the week is gone they miss out. Just because some of you can't control yourselves doesn't mean the rest of us should have to deal with your hangups. The correct solution is to simply remove any reward from REP. I mean at least anything that can progress your character gear wise. Then it's just mounts and vanity crap and nobody gives a fuck.
Putting any restriction in is stupid. It's basically saying play every day or every week or whatever cap we set and fuck you. Daily quests are the worst example of this. Blizzard has progressively moved away from this over time and I'm not sure why they had an about face on this. Remember the change to VP from heroics that let you get away from doing it daily and 7 weekly? It's same thing with dailies man. In fact I'm shocked they haven't done this same thing with the daily quests, although it would be far more painful as dailies suck dick anyway you'd be grinding out god knows how many quests. In any event that just goes to show how limited and forced these daily quests are.
The entire thing is one big fucking cock block for no good reason for the consumers. It does buy Blizzard plenty of leway to get more content out of the way and that's not a particularly good reason IMHO. If they can't do a better job of releasing actual content in this expansion when their competitors do it with less resources available to them well then that doesn't say very much about them does it.
