I have played a warden with Armour+Evasion + Spell Supression + Bark Skin as defensive layers, with Determination and Grace. For Damage Scaling using Perseverance.

This worked well better than expected, it felt very tanky in Maps. The node "Prevent Elemental Ailments from Suppresed Spell Damage" is also very good for mapping. In combination with not getting hit by attacks all that often, you rarely get ailments when leveling.

I played on HC SSF and I think i died on Exarch, because no log out makro active, and i am really bad in this fight. But the journey was fun. (Its also a bad build for bossing, because evasion does not help as much here).

EDIT:

Hoarfrost is really good defensive tool aswell. I played Ice Crash of Cadence into cold/fire conversion dual strike of ambidexterity for hoarfrost and scorch with foulborn Frostbreath.
