Hey there,
The new features for new players are… the game itself?
We’re just filling the void the game had for endgame players, trying to add longevity beyond level 60.
Performance wise, 1 fully equipped thrall is worse than 10 Frost Giants 
We’re not done revamping the game.
About the patch notes not explaining every new loot and unlock in the game. Well, that’s sort of the point. Try the patch out!
