The Caller, or VoR is a role in all common DoASC tactics. It is always done by a mesmer with VoR, but otherwise the build can vary, depending on the tactics.
Traditionally, the Caller is an experienced spiker, literally calling the spikes by pinging VoR on a central target for the other spikers to follow. In a more experienced team, the Caller is not expected to guide the other spikers, but because of the high damage potential of VoR, this role is fairly responsible, and some knowledge and ability are required.
In some tactics, but not all, the Caller brings EoE.
