Well, its true its not always true, but thats what I was trying to tell you.
Quckness may as well be the reason why your mage didn't survive just as much as it can be help to get away.
Generally I have yet to see some non-pretender like mage to get away and say: "It's only because of quickness". Of course, powerful mages and pretenders can benefit from it greatly for both combat, casting and 'tactical retreats' (running away
).
