Enhances Invigorate

My question: Is the Crit Power and Accuracy that much of a game changer to lose the 7 pie and attack power, and the extra tp from Invigorate? I would test this myself, but the prices on the Tabards shot back up so I can't afford one at the moment...I would think the AF would be better, especially if you had some Stuffed Cabbage to eat.

Found this too from Crit Damage Testing thread:

"This graph specifically shows how much increase you get by adding +50, +100, +150, and +200 critical potency (as compared to someone with +0 potency or the baseline). Because the "return" or "effectiveness" of the potency stat varies significantly with dLVL, this graph charts the effectiveness of each of the 4 cases across the spectrum of "useful" enemy ranks (dLVL=-20 to +10). To give a sample read of the graph - if fighting an R52 enemy and your critical at +0 potency does 500 damage, it would do +15% or 575 damage if you had had +100 potency (purple line)."

Looking at that graph, +200 potency at R52 mobs would add ~27%, so it would do 635...if you crit. Another graph on his testing says (basically) that each point to crit potency (power) is .1729% for dLvl0 mobs.
