I never claimed that it was a
good, idea, merely that it was
an idea.
Anyway, the only reason we don't typically see the D2 system as imbalanced is because we're so used to dealing with it. The fact that "pump Vit or die" is considered normal is an inherent flaw in the system. Newbies are not always aware that this is the optimal build choice, and suffer from sinking a few extra points into the other three stats. Ideally, in a balanced system, pumping ANY of the stats (not just vit) would be viable for any of the characters, but thats just not the way it goes right now.
The
theory behind the synergizing idea is that it would homogenize the attributes somewhat, making it a bit harder to "screw up", as it were, since stats would work in both directions. Does it make things a bit more complicated?
Definately. However, the hope is that it would make mastery of the stat system slightly less of a requirement, as characters, on the whole, would typically end up being a bit more rounded.
Its anyone's guess as to whether or not my crackpot theories would hold water in reality, though.
