Do you mod Traya offensively or defensively?

As other have said its all about the defense. Her lead is a defensive one which allows your opponents to essentially kill themselves. Between Sion reviving, the healing from her unique zeta, and Nihilus having an insta-kill you don't really need to have the team dishing out damage. You just need to survive and allow your opponent to weaken themselves and let Nihilus take care of the tough enemies.

You can toss Sith Marauder on the team if you're looking for some bonus damage, or go all in on defense and use Sith Empire Trooper with them as well. It's a versatile lead and let's you put together some very interesting team comps
