I decided to have little look see:
Wowhead, 8th comment, 17 days ago.
"Don’t store in your warband bank!
Put the first one I got in my warband bank months ago and didn’t get another until I took it out today and got 2 shards in 30 mins.
Maybe Blizz thought I already had over the max of 10 with 10+ characters having it in their warbank and didn’t drop any more."
Relevant? No idea.
I have 9, in my Warbank (just took them out) and I don’t actively farm them. *Edit: I got the first 8 in the first few days of Early Release while farming for the bee and skinning. I got the 9th a month ago perhaps, randomly on my druid, I’ve not really killed anything on Isle of Dorn in a while.
Are they dropping there? I thought they only dropped from mobs on Isle of Dorn.
Not following, in order to post on this forum you need an active sub, unless you mean a separate account?
If you have used altoholic and logged those characters in at some point during the farm, it may show up in a search.
