After reading the fan Q&A and thinking about Bethesda's reasoning for combining the cuirass and greaves in Skyrim, I'm now ok with the two being combined into one piece. Personally, I'd rather have more armor to look forward to, and have that armor be more detailed, than have the armor split into separate pieces. And with faster rendering times as an added bonus, (allowing them to put more NPCs on screen) it seems like they had more than enough beneficial reasons to justify combining the two pieces of armor.
It would be nice if we could all have our cake and eat it too, but it seems like they had to decide between one or another in this scenario, and I think they made the right choice.
