This is a nice
article about mixing and matching defense and resillience.
The key section states
Quote:
It is important to realize that, although 39.4 resilience provides the same reduction in crit chance as 60 defense rating, you lose 1% dodge and 1% miss in the process. To make these up you need to ensure that you add gear that grants these benefits along with the desired resilience. Agility is the stat that you will have to use to cover the difference:
14.7 agility = +1% dodge, +29.4 armor
It is generally accepted that +2% dodge is equivalent to +1% miss and +1% dodge, so 29.4 agility in addition to the 39.4 resilience is equivalent (in fact, superior due to the armor increase) to 60 defense rating.
I'm not at the point yet of being picky with my crit immunity - I'll take it wherever I can get it, but it seems to me that resillience coupled with agility is a fair replacement for defense, though a solid mixture of both is probably best.
Along these lines, does anyone know of an add-on/download/web spreadsheet that helps determine immunity (the critical calculations of critical immunity, so to speak)?
