The single target HoT spell when Divinity is on makes the spell a bit more useful but other than that, yeah single target isn't that great (only level 25 though).
Best thing I did to help my healing (no sarcasm intended) is to turn on friendly nameplates. The enemy nameplates massing my screen in the skirmishes and dungeons really was overwhelming.
