I'm curious what other players believe to be the most useful defense attribute in Arena. Is it armor? Dodge? Parry? Blocking? Obviously it is going to vary some based on class and playing style for example, blocking is not too useful for mages or bounty hunters with weapons or books in their hands, but I've seen a mage with a shield. Is it worth it?

Which skills, if any, are effective against area attacks? Can you dodge or parry a blizzard? How about special attacks? Can you dodge, parry, or block a charge or a leap?

Has anyone found LoH to be beneficial in Arena?
