No...it shouldn't. It didn't work before, and Blizzard has given no indication they've addressed the issues wrt clunkiness/balance that made them get rid of the old system.
This is an idea that didn't work before, Blizzards actively getting rid of stance dancing for warriors, ES shows no sign of being interesting or fixed in this incarnation. It should just be dropped instead of being the button pressing exercise it promsies to be.
Serpahim? By and large, its Inqusition that uses 5 HP instead of 3. Its potentially more interesting in that its shorter duration offers potential in timing it to stack with other abilities but overall, still an ability that buffs you every 30s . Possibly due a rework with the removal of Readiness.
Final Verdict? Blandness personified. TV does extra damage. Shouldn't this be a ret passive? Or perk? or whatever Blizzard wants to call the passive level up abilities?
