The aa I want to see most atm:
Detrimental Duration AA
Detrimental Haste AA (Failing that an AA to speeds the cast time of Malis lines)
Hastened Turgur's Swarm AA that reduces its reuse timer.
Additional Levels of Turgur's Swarm
Additional levels of the Hastened Ansectral Intervention
Additional levels of anything that adds hp
Permanent Illusion aa (No reason the masters of potion illusions cant find a way to make them last longer IMHO)
Overdue for all casters that have the gate spell to get a gate aa imho
Something I have been thinking of for awhile now.... An AA for a Chance to recourse something on dot (or other detrimental) casts.
Another idea I think has possiblities it some sort of AA tied into potion use and Alchemy skill.
Maybe like reagent conservation of potions (IE a chance to not use up the potion) or something.
Or some other additional benefits of being the an Alchemist and potions like focus effects on potion use or something.
AA's to imbue fluffy with casts or procs (especially things we can make potions of IMHO)
Lastly anything that makes /pet no cast useful
Edit: fixed a typo
