Elder Scrolls Online's player-submitted build column is a look at the so-called "Dragonknight Healer." This build is primarily focused on survivability and support, creating a very durable character that can patch up allies on the fly.
"Though her build may be missing some of the advantages of Templar and Sorcerer healing, you give her a call if you need a healer that is sturdy and really hard to kill," player Ville Korpi wrote.
The build doesn't come without offensive abilities, as it contains both multi-mob and single-target DPS as the situation warrants. It's not a boss-killing build, but for those who can heal like this, chances are that they'll be invited to groups where others will do the dirty work while this build shines in the support wings.
