What ability would you like to see added for your Job in the Expansion? (theorizing)

[Skeith-Adeline]

For a BLM, I'd like to see...

Trait

Assured Cast: Able to cast the next spell through interruptions, while moving.

Double Cast: Swiftcast now allows you to instant cast twice in a row; first spell outside of GCD.

Deep Freeze: Blizzard casts now have a 20% chance to apply the Deep Freeze status on yourself. The next fire spell cast will deal 40% more damage.

Abilities:

Oil (Off-GCD): Places a debuff on the enemy that increases Fire Damage dealt by 10%

Burst: Deals AoE thunder damage and subsequently places them with the Thunder debuff.

Penance: Deals major fire aspected damage to enemies under 20% of health. Off GCD. Places Astral 3 on user.

EDIT: I'd also like to see us get an ability similar to Quelling that, you know, works better lol. Maybe something similar to Shroud of Saints from WHMs
