The first part of your question is somewhat reasonable. The question about Sigil gets asked daily and has been answered several times. Please search and read before posting.
I have a question on some optimization of gear. I am running into some confusion as to which site i should be using for gear optimization. Shadowcraft, appears to be using old tier 12 stat values, while askmrrobot, is even worse with tier 11, but you can change them to tier 13.
the second part is specific to the kiroptyric sigil trinket, now the base value listed here make it one of the worst trinkets available, and this is supported in askmrrobot, yet shadowcraft puts it in the top for upgrades.
Just alot of conflicting information out there, and i was hoping someone can shed a little light on my confusion.
