Should shield blocking be effective against magic damage?

It makes DRK more versatile, since he always have at least one additionnal tool, whereas PLD and WAR can have zero or two depending on the figt.
Well, and since Foresight is used as a cross-class, DRK has access to 1 magical and 2 physicals, PLD 0 magical 3 physicals and WAR 0 magical and 2 physicals.

PLD has rampart + sentinel its all reduce damage
war have vengeance + inner beast (thrill of battle if u count that too)
so the other tank have 0 magical? huh?

yea bcause DRK have nice magic CD, its not like gonna be good at all
lets see if the battle have full physcal tank buster, is DRK have a good CD beside shadow skin and shadow wall? dark dance is 30% chance so im not gonna relly on that, and all the other tank have foresight
PLD have bullwark + sheltron (which guaranteed 100% block and 30 sec too, nice !)
war have inner beast per 5 stack wrath

and how much is battle with magic damage tank buster? i dont think that many
