I wouldn't even mage. Just go straight into the special. Reason behind that is players can hear the mage coming so they'll turn protect from melee on. All the rushing going on means people are prepared with quick prayer = protect from melee and their sound is on.
Don't use mage at all just come in with the spec. Reason is that people are so used to being rushed now that they play with sound and quick prayer as protect from melee. They hear the mage and turn the prayer on before you get there.
