I would like the progress in each path to not be erased with every completion of it. The fact of having to do 5 runs for 1 boss every 5 days with what I assume are not great drop rates, is very displeasing, and even worse is to think of the rewards from the final boss of the event in which players have to do 25 runs to attempt once, win or lose. I believe changes like this should be seen around all content with low drop rates, including things such as Legion & Prov, because it becomes highly annoying to players to have to redo already completed content just for the sake of doing 1 mission which is your real goal. Especially when that goal, is a fight which can easily be lost, and even if won, provides a small chance at reward.
