Dealing with self Rez is not difficult if you are aware of the situation. You need to check your enemies load out before the match so you understand what you are up against. Rounds 1 & 2 you should not have to worry because a super is unlikely that early in a match. After that you need someone with a shotgun to watch the sun singers orb. If they resurrect, shotgun melee combo to sit them back down. Taunting afterwards is optional.
