Yes it would work.
No, it's not the best accessories for axe mechanic.
Def penetration will always trump 100atk so PDM is needed. Arquiens will always beat PDM in 99% of cases. It's BiS for Axe Tornado.
There's no cast delay you need for the skill you are going to use for axe.
The best setup for axe tornado leveling is:
+10 Workers cap or flapping happy wings
Mob scarf
EDA
Malicious Tornado Axe. True howard only if you can One-Shot mobs.
Temporal Str Boots
2x Arquiens of mad berserker.
For MVPing instances, You're stuck with the supplemental armor set and Sea captains hat for Axe Boomerang.
The reason Arquiens and worker's cap is BiS, it's a skill modifier. It works the same as a True Seyren or any other cards that increase a specific skill's damage by a %.
