not necessarily, there are people who're so unlucky they can't even get to -4 CR without using SCs, let alone getting the day to farm excess stuff. Wanting perfect event units is normal, there is always that degree of completionist considering this is sort of a 'collect every girl into your harem' type of game. A week break is not too much to ask for just to get some time for aff farming, especially considering even long time veterans (sort of) like Lafate is needing aff for his girls as well.
also, Eab, it's not only casuals.

Tenhou and Overload are examples of spenders who're supportive of a week break. Unless there's double drop rates like Charles mentioned (on page 2), and regular star events well spread out, that 1 week break is going to be helpful. Yes, the 6 week break was too much, but having no breaks is too tough as well. You should never be on one extreme end of the spectrum.
and fyi, if they're going back-to-back, right after star event, we're getting 2 unit farm events (yurina and charlotte) before awakening (assuming things go like in dmm.jp), so how do you expect we level up + aff solano so we can try using her? and hell, do you really think everyone is prepared for awakening?
