The only nerfs sunsingers need is to remove the ability to revive others while your reviving yourself and getting an overshield without killing something. Its the only class aside from defenders that cant outright kill some one. They have to wait for grenades to recharge to do anything just about. Viking funeral is fine, most of the time the people who complain about that are camping snipers who cant be descoped or challanged bc they are covering the entire map with ads. I should be able to burn them to death with 2 firebolt grenades.
