Exactly, you shouldn't act that way just because you can res. The oversoul is still the oversoul. But when a guy goes down its good to know he's a Sunsinger and you've still got a full party of six to take down crota. That being said, it's good to have a mixture of all classes. 2 Titans, 2 hunters etc... However, if you've ever had a Sunsinger swordbearer go down on your team and resurrect just to kill crota and save the day, then you can talk to me again and why Sunsingers are so bad for the crota raid. All classes are great and each has their own potential.
