It's not so much the dice rolls that are the problem...but, they kinda are...let me try and explain what i mean

It isn't so much that going back to Morrowind's style of gameplay is a bad thing. Like you said, a lot of games do that and do it well, even today (Baldur's Gate 3 does Dice Rolls for everything too, and its great) it's more of is Bethesda going to keep it intact (either completely or modernize it) and risk potentially alienating the part of the fans that have only played Skyrim (A large part of players, at least from what I've seen) or are they going to scrap it and replace it with a more Oblivion/Skyrim system, thus potentially alienating the ones that are wanting an Elder Scrolls game to go back to when there were tangiable RPG mechanics in there (and that's not assuming they don't try and have it both ways...IDK how that'd look, but if you try pleasing everyone, well...).

Did that make sense? I'm kinda running on an energy drink and a dream atm

But really, i think it's more of they looked at Morrowind, Oblivion, and Skyrim, and just went "out of those 3, Oblivion's the one that could use the tuneup the most" (again, it's the redhead middle child, sandwiched between the much more universally loved Skyrim and respected older Morrowind).

Dice rolls!! And now I want to replay Neverwinter Nights..
