My rewards drove off a cliff as soon as 2.0 dropped and unfortunately, each season just manages to get worse.
With the new daily quests, they treat whatever is chosen for your focus as a bonus similar to the Gold Foil bonus. So if you have a death focus and water, you still get the focus points, you just don't gain a bonus. Had you played death in that scenario, you'd get an extra 10% per death card you played.
They also changed it so whatever your focus is, isn't guaranteed to be available every battle. I think this one had more to do with the new ability-based focuses and the splinter focuses not being available was just a byproduct. I think this is also why they changed it so you earn focus points no matter what you play and then every card you play that's inline with your focus gets an extra bonus.
