I’ve tanked endgame content on every class in ESO, and the biggest shift in recent years hasn’t been a single class buff, it’s been subclassing and scribing.

Before subclassing, base class identity mattered more. Some classes simply didn’t justify their slot in optimised trial compositions. A Warden tank often felt redundant because a Warden healer would already provide Expansive Frost Cloak. Nightblade had strong mitigation and ultimate tools, but building fully into the class often meant sacrificing group value elsewhere.

Subclassing changed that dynamic completely.

Instead of committing to an entire class toolkit, you can now build around a strong foundation and layer in specific skill lines where they add value. Winter’s Embrace can be used without duplicating a healer’s role. Siphoning can be added for ultimate generation without compromising the rest of the build. Skill lines that were once niche now have clear structural value in group optimisation.

That said, subclassing increases flexibility, it doesn’t erase the importance of a strong base foundation.

From my experience, Arcanist, Dragonknight, Sorcerer, and Necromancer still provide the most consistent trial value as core tank foundations. Subclassing enhances them, but it doesn’t fundamentally change which bases feel strongest in real endgame scenarios.

I spent most of my trial tanking career as a Dragonknight Main Tank, and it remains one of the most complete and reliable options in ESO. Its sustain, mitigation, and debuff control make it extremely stable in organised groups.

During the Necrom era, I shifted heavily into Arcanist for dungeon and arena content. The difference in efficiency was immediate. Group damage output increased noticeably, and overall control felt smoother. I completed every dungeon trifecta on Arcanist, and it remains one of the strongest dungeon tank foundations available.

Sorcerer has grown significantly in value and now stands out as one of the strongest Off Tank foundations due to its sustain, utility, and ultimate synergy.

Necromancer continues to excel in coordinated trials because of ultimate generation and Major Vulnerability, making it a consistent Off Tank choice in organised groups.

Warden still provides strong defensive support, but its base value in trials is often limited by healer overlap. It performs better when its unique tools are integrated through subclassing rather than as a standalone foundation.

Nightblade remains powerful defensively but demands tighter resource management and mechanical precision. It’s viable but not forgiving.

Templar can tank all content, especially with subclassing support, but it lacks a clear competitive edge in optimised trial compositions.

Subclassing and scribing have made more skill lines relevant than ever before. However, the core principles of tanking haven’t changed. Sustain, mitigation, and group optimisation still determine which foundations perform best and that’s unlikely to change even as class identity adjustments continue.
