My opinion on the matter is: Making people do dailies for event reward is painful. The dailies don't provide any reward, enjoyment, or enhance the gaming experience for players. This is more of a chore they are forcing player to do.
It's boring use of time, it test the player patience, and puts the player in a negative mood.
I would of loved for this event to use something other then Todays to provide reward. Something like, do 13 dailies raid per day would be less painful. It'll also be much more useful since that content is relevant and gives useful drops. Also these raid would be much more enjoyable to do, then doing outdated irrelevant boring dailies.
I'm salty, would of rather done this event with dailies raids instead of Todays.
