And combat in real life doesn't have someone guy in heavy armor running around getting attention while someone lobs fireballs at them. That's why I use the fencer of fiction. ANd the fencer of fiction takes on large groups with his wit and skill. Now we add in someone who's a master of magic to that either adding regenerative cooldowns via self healing or defensive cooldowns ala the ones BLM already has. Finally being lightly geared is the advantage here since what a stat does is arbitrary programming having a class a tank class that doesn't look just like the other two might actually be useful in getting people to tank on a small level
