I play as an off tank in T5. Am having some difficulty

- I start to kite the 2 snakes about 10s before the 2nd dive sequence starts. What is the best kiting route?
- After the 2 snakes pop, what is the best way to grab hate - shield lob or flash?
- when pulling the 4 snakes back to the LB rendezvous point, I took a shitload of damage? Should I pop defensive CD when running back? Or should I keep running and shield lobbing the snakes to raise hate?
- After reaching the rendezvous point, many a times the 2 new snakes will attack the healers or meless despite me spamming flash. And beacuse I am spamming flash, I dont have time to activate all defensive CD. How do you guys do this part?
