The armour system in Skyrim wont have seperate helmets, instead they are part of the suit itself kind of like how it was done with the ME2 DLC armours. I believe when asked why Todd Howard said something along the lines of trying to stop people taking advantage of enchanting seperate pieces of armour to have a certain percent of chameleon or something then equiping all the pieces and having the total chameleon effect as 100%
I certainly hope you're wrong on that account, because I would be rather dissappointed if they simplified the armor slots further from Oblivion. I actually want them to go back to having seperate pauldrons and left and right gloves like in Morrowind.
If they want to keep players from using 100% chameleon, they can just, oh, I don't know, put a cap on how high your chameleon can go? Like Oblivion already does with armor? Sure, it limit's players' options somewhat, but not nearly as much as reducing the amount of armor slots in the game would. Putting a cap on chameleon only effects players who intend to use chameleon, reducing the amount of armor slots available effects EVERY player who does not plan on going around naked, seeing as presumably, clothing would not get more slots than armor. It significantly reduces the amount of customization available to players, and when you're making an RPG, customization is something you're supposed to try to increase, if you can't do that, at the very least, you should not reduce the amount of customization available between games.
That makes me wonder how you've played TES games...
Acting like Morrowind was a well balanced game makes ME wonder if you've ever actually played it, because it wasn't. I love Morrowind as much as anyone, but it was very poorly balanced, and there were many ways you could make yourself very overpowered. Now, I typically don't take advantage of this that much, because it removes the challenge from the game, which makes it boring, and Morrowind already becomes easy enough at later levels even if you just play normally, but that doesn't change that there was indeed a lot of options that could make yourself overpowered.
