Compared to a fortefighter they do more damage with the same weapon as a protranser but, they are very weak when it comes to range thats why they have a real hard time against Jarba's and or things that can fly.
fortegunners do more damage all untill you cme across monsters that are resistant to bullets and status effect takes to long compared to a protranser using a trap and axe.
Fighgunners don't have a axe or a shotgun.
wartechers don't have traps, 30's, or heavy weapons.
Guntechers are nice but, their weak when it comes to melee on harder levels.
And we can always drop a trap and use a axe if we're being challenged by a fortefighter.
Some monsters are resistant to bullets, melee, magic and or traps.
Also some are small, medium, large, mini bosses and cut scene boss.
And yes we master large and min bosses. lol go protranser.
