News of the new Siren had been posted on Kotaku. The article takes you through the skills and new features of the revamped class.
Tinkering with my skill tree and choosing which abilities I wanted to invest in, I noticed where this new Siren took a left turn. Maya is much more of a healer than her predecessor. The new Phaselock ability is mostly responsible for this. It's also mostly responsible for how utterly amazing the new Siren is.
