Yes, malefic II and combust II (now instant cast) are all we have for single target at level 60. You get earthly star at 62, which is weak DPS wise but a very strong heal. Minor arcana at 66 gives you the chance to turn a useless card into either a heal or a nuke stronger than Malefic III, which can be great while soloing.

Unfortunately they simplified all the healers this way, so you're pretty much applying 1-2 DOTs and then spamming your nuke spell.
