Templar/White Monk is one of the best offensive combos in the game. I had a Bangaa that was that combo and nothing else, and he absolutely wrecked everything. Haste, Chakra, MP-Damage attack, Silence, 2 distance elemental attacks, and a bunch of other things paired with polearms two-square attack = Mobile Oppression Fortress. Not as strong as Dragoon/Gladiator(Another Bangaa I had was this one,) but the ability to cure and haste himself far outweighs the slight damage drop.
Loved that combo so much, Bangaa Templar is my POL Handle Image.
