The current state or DNC compared to it's previous EW equivalent is horrible and feels awful to play.
DNC is supposed to be a priority based reaction job and resource managment was a huge part of it.
In DT DNC now has 5 set GCD's that must be in burst leaving only 3 GCD's to use esprit on saber dances. All of the resource and proc managment is gone as now instead of pooling resources for burst and adjusting according to proc RNG DNC can no longer carry anything into burst to the point where you have to use all your procs at least a GCD before burst and saber dance before technical step so you go in combo neutral because if you go into buffs with even a combo'd fountain it will fall off resulting in lost potency since there are now so many set GCD's and using procs and combo in burst is now a huge dps lose.
Dumping everything just isn't fun and not managing procs in burst because they don't do enough damage to take priority doesn't feel good. Flourish is only used in burst to proc finishing move and fan dance 3 & 4.
The Tillana changes are insane, removing the standard step refresh from Tillana makes level 90 ultimates a nightmare.
This problem of dancer having no instant ss refresh in TOP and DSR suddenly isn't helped by the fact that all our single target GCD's were nerfed below level 94 so DNC overall feels awful in old ultimates.
The other problem with Tillana is the big obvious one. Making it grant 50 esprit was insane. Technical finish makes the dancer gain esprit from the whole party and adding an extra 50 to that along with only having 3 GCD's to use this esprit under buffs is leading to insane over capping issues. One again I want to mention the combos and procs expiring during burst because even if we did press them and they weren't a dps lose they couldn't fit in the technical/devilemnt window anyway because those 3 GCD's DNC has free needs to dump this crazy excess of esprit we suddenly have.
Buffing standard step to the moon was a bad move. Having to use it exactly on cooldown takes away even more flexibility from DNC and means that the job can no longer benefit from skill speed optimisation like in EW.
Overall DNC needs to be fixed all of the flexibility the job was loved for has been stripped away
