Free Agent - NA
Ignore what everyone's saying, they're wrong. Rei is great at dueling and if your teammates have brains, decent at healing. (Grouping is an essential part of this game)
Obviously having a second healer is good, but you can do without.
Just spam Spirit Link and get that sweet sweet CDR, and with Future Generations taking damage is a good thing, allowing you to heal yourself with the first set of bounces then your team with the second. (Even use Spirit Link on enemies)
