And, again, let's be clear that this isn't a problem if you have a whole week to complete the GalChallenges and only need to unlock it with dailies once.
I'm opposed to making this a daily event rather than something you play any time during an entire week. The first one becomes a chore, "I have to do this to keep up."
The second one, the one where you get a bunch of things to do and a whole week (or 6 days for you b/c you unlock it at the end of the first day when you're ready to go to bed), that's an opportunity to time shift the game so that when you want to play, there's something to do, but when you're busy you don't have something you're forced to do.
So as we get closer to release I'll reiterate that going for single-day Galactic Challenges is a bad, bad move. We already have tons of single-day events. Challenges should be something new, and something that allows the player to maximize fun - and if you can't choose to play it when you've got the time to enjoy it, then you aren't maximizing fun.
