20% from weapon, 10% from hotheaded, 5% from gloves, 36% from amulet... some amount from potions/buffs, and the rest from Wits. The majority of crit is not based around Wits, it's based around gearing and other factors. Anyone can do that and all you have to do is fill in the rest with Wits. It's threshold based and doesn't scale.
You can say 'crit based' but it wouldn't do to call it 'wit based' because there isn't any particular focus on wits. In a matter of fact most of your weight is going to be in Str or Int.
That's really why I was confused; if you combine this with round robin initiative, and also add in factors like scripted fights and artificial amounts of initiative, then Wits by itself is weighed fairly low when looking at the entire picture. Buffing Wits doesn't seem that far off (not saying if it is right or wrong, just saying that it wouldn't be too bad to consider).
