Gilneans will shapeshift into Worgen as the moon rises, beware! The Shadowfang and Moonrage packs always duel at high moon.
3 Worgen's spawn every 15 seconds, in one lane at a time. AoE Minis like Pyromancer and Flamewaker are good counters along with Unbound Minis. Polymorph can be used to remove Armor or Resist from the enemy push.
For every PvE mission, there is a campaign version and a Heroic version. When you first begin the game, you can only participate in campaign missions. Upon collecting 50 sigils, you will then unlock Heroic missions.
Campaign missions will grant rewards after the first successful clear with ANY family. Heroic missions must be completed with EACH of the 5 different families in order to receive the mission rewards.
