Don't you think that it would be Sunday and Monday that would be busy then, rather than Tuesday and Wednesday? If it resets on Tuesday (like all reality does in this game), then you'd have 1 roulette saved up only, while on Monday you'd have 7.

In any case I think it'll turn out fine. Sure some folks will knock it all out on Monday, or at least near the end before Tuesday. However I think that for the people who actually care enough about tomes/more exp enough to do anything but the ex roulette, they'd be doing all the roulettes every day as soon as they came off cooldown, to get the most immediate benefit. It would really help those of us who are unable to get all the roulettes on some days due to lack of time, but on other days get through all of them and have lots of time left with nothing to do. Additionally, for people in serious endgame statics, it'd allow them to focus more on raiding more quickly after the reset (such as Alex Savage), then on less serious raiding (like Alex NM/new 24 man raid), then finally could finish it up by the end of the week.
