After slowing skye, you can kill her easily, make sure, when she tries to turn invisible shoot a projectile to the ground, the blast will kill her. I recomend Catalyst legandary!
Using the bubble talent with DR and some life rip can make you tougher to kill , if a flank is next to you he is going to fight you w damage of the bubble , your selfsustain and DR (15% minimum)
Using your Runic Burst to force reload is great for stopping Ruckus from spamming bullets. Watch your shields though, especially if the Ruckus is carrying Wrecker.
Yagorath is perfect for massive shock pulse chains, she is easy to hit during her planted form and the shock pulse will chain into her team and deal good damage.
