Loreley healing is like warlock rifts. Not op, can be killed by various things. Examples: Dogs, 20 of them kills instantly. Colossus missle, 100 res and still instakill and removes restoration Yeeted off map or into walls. Incenditor cabal backpack instakill even with 100 res, 2x solar res and concussive dampener. Lots of cabal shotgun in gahrlan encounter. In harder content they are even worse, tested it myself. On Other Hand love having a rift when needed and finally using elemental wells to generate a lot on kills. Titans are finally tanky War machines that generates lots of solar wells. How did bungie say? Titans keep that engine running.
