Bitch role
From Guild Wars Wiki
A bitch role is a position in a team that is generally regarded as being incredibly easy to perform. While some roles such as backline, frontline and disruptive midline such as Rangers and Mesmers often require very specific skills to perform effectively and the success of team as a whole can depend quite heavily on their performance, a bitch role is quite different. This position is often very easy to play and even a mediocre player can often get the required level of effectiveness from such a position. A good player playing a bitch role will still be more effective than a mediocre player, but the skills required are more general skills such as kiting, pre-kiting, positioning and knowing what to do at any one time.
Due to the nature of bitch roles they are often used to conceal weaker players in a guild or team and are the spots that are most often filled by guests and PUGs.
Examples of bitch roles would include builds which contained maintained enchantments such as Strength of Honour or Life Bond, severely limiting the available energy for using skills leading to a fairly inactive playstyle, builds designed to maintain skills on a party such as Tainted Flesh or Vital Weapon or builds that purely act as a spike assist by activating a damage skill on a called target whenever a spike is called.
Often, the Elementalist class functions as a fundamental bitch role, utilizing both easy-to-use AoE skills, usually Fire Magic, and a couple utility skills.
