I make no statements about the class here. Just going to give some numbers.

Below are fist and second place in damage dealt in war front that just ended
Sabateur DMG: 84605 Kills: 29 Killing Blows: 19
second place DMG: 30648 Kills: 15 Killing Blows: 5

Second place in damage did 36% as much damage as the top, a saboteur
