I know there's a list on the arcane guide here on MMO-champ forums, but I just want a clarification as to why it says that Relic of Yulon is better then both Light of the Cosmos heroic and Essence of Terror normal all 2/2 upgraded.
Currently, I have all of those 3 trinkets, and I'm not sure which one to use. According to askmrrobot, Essence and Light is the best choice, but the guide here on the forum says Light and Relic. My current ilvl is 504 and I go for arcane mastery build.
Also, I guess its too early to say, but have someone made some calculation for trinkets for arcane in 5.2?
