Corrections to the OP.
Raina Temple uses dual pistols, and is not a 'Ranged Healer.' She is a dps (Gunslinger), identical to Vette, Andronikos, etc.
M1-4X's information is copy/pasted from Elara Dorne right above him. He is also not a healer, and is not romanceable (although that would totally be awesome). He is a tank.
If Zenith is romanceable, it's news to me.
All Fixed, Zenith is speculation from another site, I just copy and pasted over. However until confirmed I just added a double ?.
Thanks for the info.
