Does it even really matter this time? I took a quick look at the exalted trinket for frenzy, basically just a fancy haste trinket which really doesn't do hunters any good. I like the chance of getting the mount from the disgusting jar though. The exalted oracles is a nice boost to critical strike which is nice for any spec of hunter, but especially MM. So I guess that I've already answered my question and should choose oracles. Still I do kind of wonder if it would really make that much of a difference.
I don't have a raiding guild due to actually having to work a ton and going to university so I don't really take into account raid viability. The occasional heroic sure, but will a single trinket really make that huge of a difference?
