Scroll of Resurrection specials, perhaps, given the lvls and they're all in greens bought from Cata vendors (at least the few I looked up on the armory did, couldn't be bothered trying to remember the worse keyboard-mashing names lol
). Certainly appears like botting in some form, if they were all guilded (some are, but a lot aren't) or doing appropriate lvl content I'd have thought extreme multiboxer, but Botanica? Shame Battle.net's broken and that in turn has broken the raise a ticket interface, oh well, if I see it again I'll raise a ticket then.
