And DPS is more important in a lot of those such as laghodessa raids. With enough DPS you can render both spiders unconscious for the entire battle.
lol, i had a feeling this entire time that the dawn rings argument was made in the context of something like laghodessa, where its just a stunfest. lagho and GS in itself is an exception to the usual style of raid gameplay. It's also why dawns are good there, and also why spears are the best choice. this is hardly the case for RT, or future raid runs.
