Dragonknight Mobile Tank

This build relies primarily on light armor and Breton passives to have an abundance of magicka for defensive and control abilities as well as sufficient damage and self heal to maintain aggro. This tank can withstand a lot of punishment from spells, as well as equipping two pieces of heavy armor (preferably chest and legs) to benefit from some heavy armor passives.
Razor armor must always be maintained to make the build work and damage shields are used to mitigate damage if you find yourself taking a lot of heat.

Rotations
Before Combat:
Always have razor armor and green dragon blood up for maintenance.
Basic Rotation:
Charge in with invasion->burning talons->flame lash any but the invaded target (if multiple mob)->power attack-> ransack to taunt a high profile target and gain Armor
Additional Steps:
Stone Giant if more armor is needed or if a target is running to attack an ally (also might allow for the Flame Lash combo for heal)-> invasion+ flame lash or ransack multiple times to stay mobile and generate aggro while stunning enemies.
AoE Rotation:
Burning Talons->weapon swap-> Eruption-> normal aggro and taunting
Survivabilty:
Harness Magic (mainly if fighting casters or regular enemies if stamina provides)->Igneous Shield->self heal in the form of invasion/ burning talons+flame lash+ power attack OR Green Dragon Blood if magicka provides.
Boss Rotation:
Since there is only two bars a couple of skills will be swapped out the bar is as follows:
Inner Beast or Ransack for taunting, Igneous Shield or Harness Magicka (depending on boss type), Invasion to stay with mobile boss, Green Dragon Blood to heal if needed, and Razor Armor for obvious reasons.

Equipment should be used to max out health first then raise stamina for blocking and bashing. Magicka is handled through armor and Breton passives.
Light Armor and Heavy Armor could easily be swapped in and out with proper addons for applicable situations.
