Was always curious what people preferred. Do you like smaller tiers with more unique encounters or larger ones where some fights may mesh together?
Also, how many raids per tier is your ideal? Intro tiers the last two xpacs have had 3 raids, whereas each tier afterwards in the xpac have had 1 large raid.
I felt 16 was a bit large for tier 14, but 12 feels good for a middle tier. I wonder how it'd be if the middle tier were 2 raids with 6 bosses each. Would that be a plus or negative for you? I guess it depends on how long a tier is out too.
