copy-paste of what I also wrote on facebook:

Gree, if you dislike spending manpower on the epic boss, here's an idea: replace it with the same image every week and scrap the boss armor drops and replace those with champion chest keys every few levels. You can then also re-introduce the new boss milestones without cutting off progress for newer players, since they can get their first batch of OK armors from the champion chest. (also fits the general game direction of only having to craft an armor every few weeks and not needing more than 1 armorsmith)
