Sheeping

A slang term for the use of the Polymorph spell, because it changes the target into a sheep. A caster who uses the Polymorph spell may be referred to as a sheeper.

Strategy
Everyone should know who the sheeper is sheeping, and that should be determined before combat, and the sheeper should warn against performing any AoE skills. (Some procs may perform an AoE attack.)

If sheeping is broken for any reason (such as an AoE skill or another inadvertent attack), the sheeper should know better than to try sheeping that same target, especially if they are currently being attacked and it appears obvious. Then the sheeper should tell the person that is violating this and remind them to stop doing so. After all, there is probably a target that more people are attacking so that they can kill that one faster.

Take a look at Main Assist for reasons why people should be /assist'ing rather then targeting and how its best done. AoE can be effective, but if other CC is working perhaps AoE should be avoided.
