An example of the previous attributes system not being so obvious

Yeah, attributes are one of those things that Bethesda hopefully fixes and reintroduces for TES VI.

that didn't answer the question.

In MW & OB Dunmer had a starting stat of 30 in Willpower which is the lowest rank. Yet they are supposed to be experts in Destruction magic. Destruction is governed by Willpower. Sure Dunmer get a +5 in destruction skill. That is simple to see the effect. However the number given for Attributes is nothing to do with the number given for a skill. It does however determine growth.

How then are the attributes logical? Why are Dunmer the best destruction mages when they are 30 willpower?

The system is not that obvious. Not every gamer will want to spend the time trying to understand a complicated leveling system. They are more interested in playing the game with a system that is logical as they go. It is the gaming experience rather than the reading of the manual.

Deciding on what skills, play through approach (head-on, stealth or magic) & equipment is a much more natural that pre-designing whether you can carry loads whilst still being able to take a whack or whether you can carry loads but not take a whack.

Attributes the way the ywere in Morowind and Oblivon had its flaws yes, but they should improve them rather than remove them.

So now that you have found a flaw in that system, explain to me why every one runs at the same speed and jumps the same height in Skyrim? Why can't my character be strong?

Skyrim has no way of telling me what my characters strenghts are only what my character isskilled in and that is a far worse flaw than the dunmer thing which most likely was simply missed by the developers.

I agree that warriors should be more able physically. That way it counteracts some of the extra weight they are carrying in their armor and weaponry.

How is it difficult to grasp?

Dunmer are skilled at Destruction magic, but not necessarily strong-willed. It's like a D&D race having -2 Wis, but with a +2 CL bonus to casting spells that inflict energy damage.

Likewise, being a skilled conjurer does not necessarily mean that you're intelligent in any other way than binding a creature to the Mundus.
