To counter the new defensive levels coming with the March 2016 update for Clash of Clans, Supercell plans on adding new levels for the following troops: Hog Rider, Goblin, and Valkyrie.
Teased today, the Hog Rider will increase to level 6, the Goblins to level 7, and the Valkyrie to level 5. Additionally, Valkyries are getting tweaked; their damage will be increased, hitpoints decreased, and the troop will start attacking much faster after reaching her target. Goblin level 6 is also being moved to Town Hall 9 (it was previously Town Hall 10).
While we’ll have to wait for the update to drop before we see specific stat increases and exact numbers, a preview of the new troop levels in action can be seen below.
