Honestly, the fact that favors are much easier now and that I have to do less to get the equivalent is fantastic imo. I was already 2 star before, but I was able to do heavy crafting over the past few days and am now 3.5 star on weaver and almost 3 star on everything else. So I can craft most of the IW pieces to help FC mates upgrade as well. It also helps that moogle give you 2 tokens per quest once you reach rank 3 or 4, whatever it is.

Oh, and the modified Raths rotation for 2 star still works on 3 and 3.5 star
