It looks like Blizzard is working overtime churning up patches for its bestselling MMORPG, the World of Warcraft. Patch 2.2.2 has just gone up on the live realms and now patch 2.2.3 has gone live on the Public Test Realm (PTR).

Blizzard posters Hortus (on US Realms) and Salthem (on Europe Realms) made the announcement earlier, together with the patch notes:
