Well in terms of Charms, after getting my 3 for the week, I've still got another 2 weeks worth of lesser ones to hand in, and I'm only honored with Golden Lotus. I think we'll be able to get so far ahead of the curve that in the long run we wont be 'forced' to keep grinding them out. Especially since you can only hold a maximum of 10 charms and I don't see (myself) using them every week, only during the inital gearing stages and on "must have" drops.
I also expect the "Firelands 2.0" dailies to reward charms.
