Well, sort of.
In your example, the 100 life would presumably have the 50% DR or whatever, so you’d need to factor that in to your comparison imo.
But ya, Trang has high life regen with Siphon Blood. The massive increase to life is actually quite nice imo.
Typically speaking 50% DR is better than 100% life. But 300% life is an interesting comparison imo. Especially if you’re constantly regenerating it so quickly.
