Non-DLC sets healer (SPC+PA) for Unorganized random group: no tank in group - Templier Construire PvE - ESO

Channeled Focus is for self-sustain, but you can always swap this skill for something else. Adding Minor Heroism and Minor Courage buffs through scribing skills. If you're using the Sorcerer subclass, you can replace either Healing Thicket or Aggressive Horn with Summon Charged Atronach. If most players in your group are using the Oakensoul Ring, you can swap the back bar’s third skill to Living Dark or Purifying Light for the Templar buff or Mender's Bond for extra shielding. 

The reason I don’t use Regeneration is that in random Vet dungeons—where players often don’t even use group chat—its healing isn’t enough when someone makes a reckless push.

The "No Tank in Group" build is what I call an emergency fake tank solution. I use it when the tank in a random dungeon abandons the group or simply can't do their job :(  It's one of the worst situations in a random dungeon, especially since most people aren't willing to wait for a new tank. As a result, the tank role often falls on the healer’s shoulders (that is, if we don't quit too). That's why I only change my equipment instead of switching my entire subclass.
