The Sentinel sure absorbed damage like a champ, but the Vanguard could be more or less invulnerable after being specialized a certain way, plus the Vanguard could wipe the floor with literally any opponent in seconds. I mean, it depends on how you played and how savvy you were with the controls.
The Vanguard was far and away the most devastating class in Mass Effect 2zĭo you mean least? I thought Vanguard was by far the most difficult class for an insanity run.
