I also noticed that The Sigil of Minor Accuracy will gives LOADS of more crit then then Sigil of Superior Accuracy when fully stacked. Thoughts on that?
I think the build editor you used has mixed up the Minor Accuracy description with Sigil of Perception. Minor Accuracy adds 1% crit chance (Major adds 3%, Superior 5%) while Perception builds up 25 stacks of precision, similar to Sigil of Bloodlust for power and Sigil of Corruption for condition damage. (Maybe you knew that and were referring to perception in your post, but I thought new Guardians might be confused.)
