For those of you thinking this trinket sucks think of it this way.
Defense, whether you are a druid tank, a paladin tank or a warrior tank, you need it. For some of these classes, for example a druid, you would rather have dodge and agility and etc., but you still have to make the defense requirement. This helps people reach the 490 or 415 defense they need without using tons of gems, enchants or equips that would otherwise be replaced with +block, stam, agility, dodge or parry equips, enchants or gems.
In other words...
this could be a better improvement to some people than other trinkets depending on your other equips and where you get your defense rating from.
