Battleground Healer - Warden Построй PvP - ESO

Very basic idea of this build:

• It might be more effective (when playing in a group) to have high mitigation (50%) against high burst than high health.
  • we can have relatively little health while our stamina sustain is solid mainly through dark deal.
• Skills like Force Pulse and Elemental Explosion are the strongest ranged options for AOE damage. they hit very hard.
  • Learn to cycle trough the player that you attack. A player need to have a status effect then you can already target by proxy.
  • Else: Elemental explosion + ulfsiilds + Magicka detonation is a good burst option.
  • You can create no go areas with mines, ice fields, templar slow, etc.
• Buffsets are over the whole group more effective than sets that apply only to one player.
  • After that we might use: Powerful Assoult, Meritourious Service, Sanctuary, …

If you play in a semi competent group it will be very hard to just dump ulti on you and burst you down as heals and shields scale really well. If you're somewhat solo and under more pressure you might invest into a little bit more sustain and a bigger stamina pool. 

• This build is also slightly easier in CP PvP as the first breakfree is free.

Basically I took the three skilllines that offer significant sustain and good healing. Other options are:

• Warden: Winter's Embrace
• Warden: Green Balance
• Other player could take those skillines and also wear buff sets  and Esoteric Environment greaves.
