For low level duo like you're suggesting, it can work, but then again, so can sword and shield, or club and shield, aslong as you keep your JA's and ws flying, your WHM shouldn't pull hate, WAR is the most versitile job in the game when it comes to it's arsenal, and it's up to you entirely how you use it Though for all intents and purposes, try and keep your GA skilled along with whatever weapon you end up using as at the highest levels, you'll end up using it most.
