It was pretty restrictive in a way. It forced you to stop whatever you were doing and go practice in order to get 5x multipliers on your stats.
Sure, they could've gone the nGCD way, but how is that different than the situation I mentioned above?
Attribute still affect things with nGCD, while no attribute mean you need to find a something to:
- Determine encumbrance level
- Determine magic resistance level
- Determine starting health, magicka, stamina
- Determine character speed
- etc
But these will all be static, while attributes can be drained, stunned, damaged, etc... Also, each race had different starting attributes (male and female at that), without attributes races are just a starting "perks list".
