The first to third waves of monsters were actually fine, and most teams could handle them.
The problems started with the fourth wave of monsters, where a Necromancer would appear. They would stand still and lock on to the closest player before channelling their spells. As such, the players needed to keep a Secondary Tank at the rear as a reserve.
The Main Tank would be unable to withstand the damage at the rate that it was dealt.
The Necromancer also had to be controlled with Fears or Polymorphs.
The moment the enemy wave engaged, the melee players had to focus on attacking the Necromancer while the ranged players and the tanks would focus on dealing with the rest of them. When the Necromancer was almost dead, the melee players had to turn to the monsters and help clear them out. Once the monsters had been cleared, they could then deal with the almost-dead Necromancer that had been constantly crowd-controlled.
