First of all, they appear to be making first rd matchups that pair the actual hws together, and the lhws, whixh makes sense. If every fight was hw v lhw in the first rd, a lot of the lhws would potentially get bumped right away just due to size, which would be deemed unfair.
Secondly, how or why would you rather see rampage v fedor over mir v fedor?
Mir v fedor is one of the fights pride v ufc fans have wantes to see for years. Ufc champ v pride champ, etc.
Seems obvious that mir is the most ineresting matchup for fedor, and the one fans would love to see, as fedor never went to ufc, so we missed out on great hw matchups like fedor v randy, brock, mir, velasquez, etc.
I'm baffled that you'd prefer to see him v rampage, though that would be a fun fight back in the day.
