In playing crucible the number times I have killed a sun breaker is just slightly more then the amount times I have been killed by one. If you kite them you can win a lot against them. If they kill you good for them they found a good spot to use their super. On average they can get around 2-4 kills per a super. I don't know about you but with blade dance(if I time it correctly) plus encore I can get that same ratio. If you even hesitate for a second to slam two golden gun shots into their chest then you deserve to die tbh. Nightstalkers one shot into them and a second or so later they are easy to finish off.
