I'm looking at putting together a set for challenge modes. The only information I can find on trinkets is from early in MoP. It says that the best ones are Relic of Yu'lon and the upgraded Zen Alchemist Stone due to the high uptime on their procs.
I was wondering if anyone knows if any of the more recent trinkets from ToT or SoO beat these. I was looking at Purified Bindings of Immerseus. It seems to have an insane amount of extra stats.
I'm not very good with judging how good trinkets are. Any help would be much appreciated. =)
