Corpse control
From Guild Wars Wiki
This tactic involves the control over corpses in PvP. Against builds that use skills to animate minions, use Wells, or cause damage through the use of Putrid Explosion, Corpse control is highly recommended.
The spells involved in Corpse control are all quick casting, low Energy spells. Although the only spells that are used for this tactic are necromancer spells, the most usual tactic involves mesmers using them, due to the Fast Casting attribute.
