The game is not balanced around solo performance, it’s balanced around team contribution. Safety and solo performance are secondary balancing points. Since a sentinel does not have taunts it needs to do closer to as much damage as a scrapper, it lives very near melee with short range attacks and has only a small support element. It should still be the lowest damage out of sentinels, scrappers, stalkers, and blasters, but it should be in the same range. Right now it’s outside the range.
