Oh look.... a biased poll on the Skyrim forum. I haven't seen one of those in... five minutes or so.
Here's a bit of math for this "more sets" "less sets" idea.
Imagine the choice is between 30 sets of combined armor and a mere 10 sets of separated armor.
How many combinations are possible with the first? 30.
How many are possible with the second? 100
Let's imagine they get generous. Instead of 10 sets of separate armor, they do 15. How many possible combinations is that? 225
Now - what if they get generous on the other side. Instead of 30 sets of combined armor, there are 40. How many possible combinations is that? 40.
Which one is actually the "smaller number?"
Actually, that's not how math works. If you have 10 sets of separated armor (helmet, cuirass, gauntlets, greaves and boots) that means 50 pieces of equipment, 10 per slot for 5 slots. If you took every possible configuration, it would mean 10*10*10*10*10 possible combinations. That's a staggering 100,000 possible armor configurations.
Skyrim's armor has four slots: helmet, armor, gauntlets and boots. If they do 30 armor sets like you suggest, that means 30*30*30*30 configurations, or 810,000. Huh. That's way more than 100,000.
They're not going to have 30 sets of armor. But we've seen pictures of the same "armor" slot with different pauldrons, and pauldrons on separate sides of the armor. Presumably that sort of customization won't JUST be for armor. But say they only have 15 sets of armor, and only the "armor" pieces have customization, and that is limited only to pauldrons. Each piece can have no pauldrons, a left pauldron, right pauldron or both. So now there are four times as many possibilities for the "armor" slot. 15*15*15*60 is 202,500, still more than double your 10 sets of separate armor scenario.
