I just fail to see why dailies and weeklies are a problem. You can also stack them up and do them once every 3 days.
To me it seems you want to remove things that apparently make you "having to do dailies, every day" (which is not true) with something that actually makes you log in even more because it's literally more things to do. Not counting for the fact you're creating FOMO for people who for whatever reason are unable to get the rewards from a season pass.
Sorry, it's just a bad idea. Can work with other games.
