The way I look at it is as follows, good group with a good tank up front, slap on the str armor and go middle, as a fighter you are expected to dish damage, it seems very wasteful to me to have a very well geard pal and still 2 fighters that situp front, take more damage and do less damage than the pal or bar for instance. If its just a random pick up cat, then slap on the EE cause your likely gonna be taking damage anyway or you wont have a healer.
