Level 39 Feral Combat Druid twink build

This is a hybrid PvP control build, not a pure damage cat. Nature's Grasp plus Improved Nature's Grasp gives reliable roots when melee hits you, Feral Charge gives a 15s interrupt/immobilize from Bear, Brutal Impact lengthens Bash and Pounce, and Feline Swiftness makes outdoor Cat Form repositioning much harder to answer. Furor is mandatory for PvP shifting: Bear starts with rage for Charge/Bash, and Cat starts with energy after a shift. Nature's Focus lets emergency Healing Touch or Regrowth casts finish under pressure, while Insect Swarm adds a cheap instant debuff and hit reduction.

The gear is the stamina/agility PvP set: Adventurer's Pith Helmet and Ironshod Bludgeon from Uldaman, Fleshhide Shoulders from Razorfen Downs, Basilisk Hide Pants, and Arathi Basin boots/talisman. Scout's Medallion, Legionnaire's Band, Defiler's Leather Boots, and Defiler's Talisman have Alliance equivalents with the same role if needed. Tidal Charm is too strong to skip: a 3 second stun wins duels, peels, and flag fights.

On the survival curve, the practical knee is around the standard balance 50 set: about 1430 HP from gear and 729 armor for a 33% throughput loss versus all-damage. Pushing much past that gives only small HP gains while continuing to cut damage, so this setup keeps enough bite to punish targets after your stuns and roots.

Play by prebuffing Mark, Thorns, and Nature's Grasp. Open from Prowl with Pounce, apply Faerie Fire to stop restealth, use Insect Swarm/Moonfire while moving, and swap Bear for Feral Charge or Bash whenever a caster tries to cast or a melee commits. Heal early, not at 5%.
