Flame throw’s damage is not bad, though in a real-life case you may found out spark blast is the most spam-able skills of fortress class, especially in the PVP battle. M-3 Turret is a bit lame since it is too slow to happen, but the blow away effect has its usage when in a raid dungeon. e.g., prevent monsters from touching the core.

By the way, its EX Tathlum cannon is one of the best PVP skills.
