I have a fire/rad sentinel lvl 50 on Excelsior that's tier 3 on all incarnates that's is my main farmer it takes less damage and deal more than my rad/fire brute and my brute is is the same build same enhancements I shock a lot of people how well my sentinel holds up it take on 3-5 groups at time . So Every time I see people on the forums say that sentinels can do damage i laugh at them and say i hope they go and try it out I've converted alot of people that play brutes that ive teamed with over these past6-9 months I've played it.
