At some point CG has to decide that it’s not worth it to continue nerfing so content stays endgame. For example, cls and rjt really trivialized end game haat one year after haat was released. Those people farming GK and depending on cls and rjt mechanics will still be 1 year behind the hardcore crew ...
That said. This p3 loop depends critically on:
1- low potency on everyone
2- high speed
3- zeta talzin lead and ventress rampage
4- daka unique omegaed
Talzin lead gives 5% Tm per debuff resisted. Anakin applies two debuffs on basic, while initiate applies one (then daka, ventress, talzin also also apply some). All these get resisted and contribute to TM train.
The low gear initiate is just to reduce RNG so she dies fast. It’s not a strict requirement.
All this said, I think they changed traya so she has very low tenacity while toppled, maybe even negative. My 4% potency initiate deals 20-30 dots on maybe 50-60 attacks now ...
