Necro:
An AA that makes all dots either active or cast, act like splurt - increasing in damage every time they tick.
A splurt spell upgrade to bring it in line with the current tier.
AOE lifetap, either spell or AA.
Lifetap over time spell upgrades.
Chanter:
Channeling AA, as it was in EQ2. When triggered, it would equalize the mana of all group members...like the cleric 2.0 does for group members life...but for mana.
Pet classes:
A parallel tier of suspend minion - so a pet class can keep a third pet suspended, with its own recall trigger key, and have a choice whether to call from suspend different pet types. I.E. one dps pet suspended, and a tank pet suspended under a secondary suspend.
A summon companion AA that doesn't take up a spell gem or clicky item spot.
Inate pet run speed AA, as others have said.
A new class of pet that is strictly a nuker and doesn't melee.
Summoned gear that has + focuses on it, made for the nuker pet, or the nuker pet able to use dropped gear.
Bard:
Spell upgrade that brings bards single target resist debuff song to an appropriate level. Currently it generally isn't.
Monk:
Group FD AA - fall of the phoenix it was called in eq2 iirc.
Generally:
Augs that are more suited to individual classes, or at least better suited for roles:
"tankish" - Augs that are much less + weapon damage, and are more + ac/hp, but are meant for weapons only.
+ spell damage
+ weapon damage
+ healing
3.0s .
