Testing

Wrath Classic is adding a new difficulty to dungeons in Phase 2 with Titan Rune Dungeons, which allow players to gear up with 10-man raid level loot from Phase 1 — helping to keep Wrath dungeons relevant throughout the game. Blizzard has talked about increasing dungeon difficulty and improving loot before, originally calling it "Heroic Plus," but now the feature is live on the PTR for testing.

Testing periods are a time to find all the bugs and glitches in a video game before it launches -- or, at least, the goal is to catch as many of them as possible.
