I pretty much only use the self Res during control. I can totally cheese. Take out maybe one of three attackers when I'm defending a point, die, wait long enough for them to forget about me, self res just before the point goes neutral, kill them, and usually walk off lol. Or I run the armor buff off gradient instead of the res. With longer grenades off sunbreaker and the damage over time, a sunsinger can seriously choke off access points. Even just melee igniting someone gets revenge kills if you die easy. The self rez in nightfalls or strikes has paid off countless times. My voidwalker I had to go back to just now due to getting that Thorn bounty, and i hated it. Other than the panic button super, I just didn't enjoy it, even running with the Amakara helmet for extra armor while supering, I just felt squishy.
