WAR is most definetly the best subjob you can use in a normal exp setting and most things in the game.

-Provoke: Good for setting up SATA, backup tanking, and in cases, even main tanking.

-Berserk: I believe its +25% ATK for 3 minutes, activation is minimal hate; negligible.

-ATK Bonus: ATK+10

-Double Attack: Another strike, has roughly 10% chance of firing off. Combined later with the MNK's natural Kick Attacks, you will have a chance of hitting even more, and therefore gaining more TP, and more damage over time.

-Defender: Great to use with Provoke and possibly Counterstance(not sure).

-Warcry: ATK Bonus for people in Area of Effect for a short duration. Reletively High Hate. But this is still good to go in conjunction with your attack powers.

Minor DEF Bonus - DEF+10
