I was thinking of this earlier today and I thought of the reasons why Beth took the attributes out and just went with Health, Magicka, and Stamina. I understand how bad attributes were in Oblivion. The main problem was that the skills has a govern attribute, all the attributes made it to 100 and you had to use skills that you would never use in order to get a +5. Now with the addition of perks Beth went with the reason that Perks could do the same thing as Attributes and they can, but they can't here's why. Attributes did more then just + number per level they had effects. Strength affected encumberence, Speed affected how much you moved, etc. Not to mention that Attributes showed you where your character was and in Skyrim everybody's character is going to be the same when they start out minus some stat changes due to race and different starting bonuses in skills also based off of race.
This is what I propose, keep Health, Magicka and Stamina in but also include the 8 attributes from Oblivion. Now instead of doing a 30-100 model and then having everybody's character get to 100 stats at certain level, we could go with a 20-50 attribute setup and you get +5 attribute points every 5 levels instead of every level. The Reason for every 5 levels is similar to the reasoning that a perk in Fallout new vegas is every other level, it makes more characters diverse and it makes your choices even more important. Now of course there is a counter argument "Well what about the perks, if you do this then the perks aren't important". That argument is solved by making the 8 Attributes do mainly one thing instead of a couple things like in Oblivion.
Now since we are going with a 20-50 setup for attributes how would be determine where the races started attribute wise under this system. The 20 attribute area is in the low end bracket that's where Bretons would go with Strength, Redguards with INT, etc. The 25 Attribute area is the middle ground and The 30 Attribute area is reserved for characters that are good in a particular attribute like Bretons with Intelligence, Nords with Strength, etc. It's similar to how Oblivion started the Attributes 20=30, 25=40, 30=50 and luck always starts out at 25. This is a basic idea as to what the attributes could do in Skyrim.
Strength- Affects the amount of weight that you have. 1 point of strength equals 10 weight. If you have 30 strength that equals 300 pounds of Encumberence.
Intelligence- Affects the amount of Magicka your spells cost. For every point of INT your spell cost would be lowered by 2 points. No spell cost can go below 5 points or 10 points as we don't want 1 magic point lightning spells.
Willpower- Affects Magicka Regeneration. For every 5 points of Willpower your magicka would regenerate 1 magicka point faster. Stamina would deal with Stamina Regeneration.
Endurance- Determines how much Health you will get per level outside of choosing the Health Attribute. For every 5 points of Endurance you get an increase of 2 points more of health per level.
Speed- Determines how fast you are. For every 10 points of speed your running speed is increased by 10 % off of a base set speed.
Agility- Determines staggering rate. For every 10 points of Agility your stagger rate is decreased by 10 % off of a set Stagger rate number.
Personality- Determines how NPC's view you. For every 10 points of Personality your despostion with NPC's goes up 10 points from a base starting point of 30.
Luck- Determines how lucky you are. The higher your luck also means a higher chance at getting rare items. For every 10 points of luck the rate that an item appears whether it's a random enchanted Armor or gold goes up 10%.
This would be an example of a characters starting attributes.
Breton
Strength 20
Intelligence 30
Willpower 30
Agility 25
Speed 25
Endurance 20
Luck 25
Personality 25
Nord
Strength 30
Intelligence 20
Willpower 25
Agility 25
Speed 25
Endurance 30
Luck 25
Personality 20
I really hope that my idea is at least looked at and considered. If it's too late to put Attributes back in I completely understand and I also will be happy under the perk system since Beth fixed the flaw that Fallout 3 had with Perks. Fallout 3 had too few of perks, now that we have around 280 perks our characters will be more diverse and our perk choices will be even more important.
