Those who participated in this year's official arena tournament have been not-so-patiently awaiting their reward for playing 200 arena matches in the preliminary rounds on the tournament realm. It's been quite awhile since players expected to get their hands on Murkimus, but Blizzard representatives have been giving a mid-May estimate that proved true today.
Players who played their 200 matches should be logging into Murkimus in their mailbox today. You can stop panicking that Blizzard cheated you out of a pet. You can stop worrying that you missed some important detail. Enjoy your murloc, folks.
