Their core kit is good, and the sects' buffs offset the seemingly lower potency, but some spells, mainly their cooldowns are fairly lackluster:
Lightspeed's debuff doesn't belong outside PvE.
Sinastry should be affected by every heal, not only benefic, and on heals to yourself..
Collective Unconscious does too little for how much work it needs, particularly on diurnal, the buff needs to linger after it ends for some seconds or to be stronger.
Celestial Opposition needs a rework, for being your level 60 skill it's use is extremely niche, far more that our actual dissipation.
Now, on non cooldowns:
Diurnal's haste buff is stange, since speed buffs don't affect over time effects right now.
Diurnal's Aspected Benefic needs to be stronger, right now it barely beats two benefics on both power and mp efficiency, compared with regen's monstrous power and efficiency.
The cards could use some buffs, particularly spire, ewer, and maybe spear.
