a properly built blaster will watch a Sentinel show off & simply say not bad. Now hold my beer.
as to how much DPS can a dead blaster to? depends, how many Rad 'fenders/trollers do you have around? Because a dead teammate is just a bomb waiting to explode for a Rad 'fender/troller.
and from experience, with 7 Rad fender/trollers and a dead blaster, the answer is LOTS of damage.
and then one of them stands the blaster up, dusts them off, and says lets do that again in a minute.
