Hmm, maybe this is the case? I tried zoning in by myself, and then while I was in a raid, but maybe getting a high lvl in their first will do the trick... I'll have to make a post with an update.You guys really sure? Cause it bugs sometimes and a high lvl must get in before your twink.
I got it atleast on my 19 twink on EU. Didn't have time and possibility to get it on my F2P twink on US =(
