i don't know how long it would take but yeah i agree. these are games you can play unlimited unlike the 3 per day regulars.
t's tnt's marketing strategy to get players to stay on their site for longer period of time = more exposure to advertisements = more revenue for tnt & co.

in fact, the featured game, the dailies, plots, wars, are all marketing strategies to get players to:
1. come onto their site everyday for dailies, etc,
2. to stay on their site longer to do the plots, wars, etc.
3. to make sure players come on at least once a month for the monthly freebies. or else they'd lose players, consumers, customers, patrons, whatever us people are to them.

of course, their strategy works very well and they continue to use it because us players are all happy with getting freebies and the idea of getting prizes for the plot/wars in the end.
no matter that the prizes are given out months after the plot has ended and another is starting
