Technically all tanks are "hybrids" in that they use all three of the primary stats (Health, Stamina, Magicka). When I say "hybrid" however, I'm referring to the ability of these builds that can both tank and keep up moderate single target/AOE DPS in veteran content particularly Trials. The following setups for the Warden hybrid tank and Dragonknight hybrid tank in Aetherian Archive Hard Mode aim to optimize both debuffs and buffs for the group while aiming for at least 30k single target DPS in comparison to other hybrid tank builds that may fail to perform especially at the highest level.

Note that the Warden hybrid tank came into play for a magicka DPS composition and the Dragonknight hybrid tank came more into play for a stamina DPS composition. You can use either build(s) for whichever, it will just come down to group.
