And no, dailies are not required. For one, because you don't need to cap out your VP anyway, it's not 'required' for raiding nor PVP nor soloing. Two, because you choose to do them because you (of your own mindset) think that "quick = best". Nothing about "20 in 60" implies they're mandatory. Frankly, I could run a heroic in the time it takes me to do 12 quests.
