Summary of strat in case you don't want to watch all that:
Send in a burner team to eat isolate. Sometimes a lone g11 works well for this. Then send in your team. Topple with Anakin right away. After topple, your low gear Initiate with lots of crit chance should die. Then you can topple the second time as long as no NS are Dazed. If they are you may need to restart. Topple is best done by Anakin or AoEs so you don't accidentally rez Initiate. Then once toppled with Initiate dead and no Daze, you auto basic only.
I never knew they could also do all of p4 though. Good to know if I ever have a reason to relic NS.
