I dont know if this item is useful or not, but I have used this recipe to level my JC skill and thought I would send a couple of the necklaces to Felbane, in case it can help buff you guys in Karazhan at all.

There seem to be alot of necklaces and items in JC that give a party buff, however I am not sure if the pieces would actually nerf a charcter by having to wear this piece rather than whatever necklace they may already have.

Some other pieces:

I cant remember exactly which ones I can already make, but I would be interested in peoples opinions on whether any of these items would help with certain encounters etc, and therefore whether its worth me making a few..

THanks,

For my eye, they're very worthwhile. For example, if I used the the +2% spellcrit to party members, I personally would lose very little compared to the overall buff what the group will get. However, I see these more as a raid items rahter than items that you'd use while grouping, as in raids you have the option to switch the group composition for optimal use of these necklaces.

ok.

Well for those of you raiding, if you feel any of these would be useful towards your success, let me know and i will start crafting

(provided I have the recipe, will update the ones I have when i get home tonight)
