Do you think they will bring back different attack types like in morrowind? (slash, stab, ect)

I would say no just because in Morrowind most people would just use the "Always use best attack option" which made it a bit redundant.

Most likely there will be different attacks in a sense, as the type of weapon will have a different attack type, similar to an "Always use Best Attack" just without the list of numbers. Takes less time to make and isn't that much different.
