I haven't been keeping up with everything, so I may have missed info on this. Just saw a video where they mentioned every class can wear pretty much every piece of armor and use any weapon, and that Dwemer/Elven/Daedric armor will all be in along with the other usual sets.

Is there any info on how this is going to work? Is Dwemer going to be the best, but slow your character down? Is there going to be a tiered endgame approach that pretty much leaves all the other sets worthless?

I hope they do something like the pre-expansion Ultima Online, where every set of gear has it's uses - heavier armor for more physical defense, the lighter ones having more elemental resistances. And let us build our own custom sets with enchanting.

We dont know, we know enchanting is important, also soul gems are in the game, so my impression is kinda there isnt gear-grind, we just improve our weapons/armors instead. So choose your weapons/armors and improve them. You kill some raid-boss and get awesome soul what you can use to improve your gears. Well. this is speculation.
