DEX no longer increases evasion or crit rate. Now, it affects your Parry rate and, of course, Accuracy.

So if DEX no longer applies to crit rate or evasion, what stat does modify those parameters? I have noticed that a bit of gear increases both of those things but surely there is some other stat that they are derived from. As much as I like to High/Low my characters for party play, I also like to take classes and play them out of the box. I would really like to be able to spec a PUG to be a very evasive, almost tank-like version of the class. I understand that the roles each class is meant to fill tend to define the way the class grows, but some directional freedom is definitely something I love in RPGs. Sure I am playing a DD class, but I am playing it very differently than my friend and we are both effective in different ways. I would be willing to sacrifice a little consistent damage for more evasion and higher crits.

Anyway, it seems that STR and INT are the stats to push if you want to High/Low PUG. Is that what I am seeing here? Also, where can I find a detailed description of some of the number breakdowns? Sort of a list that shows what numbers are derived from others and how they correlate.
