I have a running tally of all the sortie earrings I've gotten, I didn't start recording the +1 cases though until a couple months in, so the number I have for that isn't accurate.
of the total 695 cases I've gotten, I have gotten an estimated 47 +1 cases (when the basement became available I started counting at 20 given the number of +1 earrings I already had using the assumed 5% rate of getting +1 from an old case)
of that, I 've gotten 4 +2 earrings, none are higher than the base value. I fully recognize my % is extremely high, being about 1/12 where the +1 earrings from old cases is averaging close to 1/20
another thing I have noticed is a slight lead in the number of starting job earrings I've gotten in total. with war, whm, rdm and thf being 1,5,2,3 out of the top 5 jobs in total number of earrings acquired. Now, that said, I 'm only working with a sample size of 695, which is relatively small in the grand scheme of things.
the +2 earrings I've gotten are rdm, pld, brd and rng, which is sad because of those, I'm only able to make use of rdm and brd.
I'd be happy to post my full findings in another post if people are interested in seeing that, will take a minute to type it all out though.
