Tank Guardian Build - your personal thouhts
I do a lot of harder dungeon content with my static group, and tanking is more about mitigation through use of skills and well-timed dodges. My near 3k toughness is merely used as a way to get aggro more frequently and to contribute to my crit chance. I’m using soldier runes to reduce/negate the effects of snares/roots that some enemies use because being stuck in one place can get you killed fast (i.e. flying shaman in volcano fractals).
I think armor rating much higher than 3000 isn’t really worth it. You’re not going to be invincible, especially when there’s a lot of bosses that use instant-down (or near instant down) mechanics. I’m not sure what you think of when the word “tanking” comes up, but in my experience with GW2, it’s getting aggro off of your allies and mitigating/avoiding lethal hits through proper skill use and timely dodges. Facetanking is mostly something you’ll find in other MMOs, and should not be applied here when facing the encounters with lethal attacks that ignore your high resistance.
