I still don’t see any valid reason why Blizzard removed it (according to their own account deliberately, rumour has it that it was a glitch but they don’t want to spend money on fixing it: I fully understand this, of course: as an indie company with little budget, the possibilities are very limited).
Seriously: It has only caused damage.
++and i would like to add: lfg dungeons is also about the whole server pool. if the line of reasoning were consistent, it would also only draw within its own server.
but that is not the case. at the very least, it is inconsistent.
