So no Lifesteal in FL4k Skills?

There's one where the Pet heals you and you heal the Pet but I mean "c'mon, nothing like "Lifesteal on Crit?" We just have Health Regen? Is that what we focus on instead of Lifesteal?

I'm curious how FL4k mains stay alive in the True Trails compare to someone like Moze who has Vampr and Rushin Offensive.
