My view is that tamers using nightmares can add balanced variety to viable PVP templates if the changes suggested by Kazzyboy are implemented. But as GluttonySDS pointed out, completely relying on multiple pets for offensive purposes (see $ and LORE guilds) is another prevalent issue that should be addressed. Currently the damage output of two trained dragons against players is ridiculous and it could be significantly decreased without rendering tamers defenceless.
