I just found that the Kazzak trinket Chipped Soul Prism have a weird scaling in challenge modes cause it gives you +93 main stat and +93 of each of the secondary stats so its over 465 secondary stats all the time! Yeah, the 93 main stat is a lose cause maybe another tirnket can give you up to 150 but the secondary stats can probably worth the lose of 50 main stat. Don't know how usefull can be for all class/specs but if this sound good for you maybe can help you to push your gold time or help you to sell some carrys

p.s.: I try it as resto druid, maybe not working for other class/specs but no really a reason to won't work imo.
