First of all, I've been playing awk mystic since it's release all those years ago.  For a long time, even after the initial nerfs, i recally the overall consensus was that awk Mystic was one of the better PvE classes. Then between succession and rework she had fallen into irrelivancy. Nowadays, post-rework, her placement in PvE is somewhat obscure. Of the few classes I've played she seems pretty good in places like stars end where you focus more on a few seconds of burst damage per pack. And in low end 1-hit PvE she is somehow on-par if or just a bit worse than succ nova, my main.

Most of awk Mystic's moves are pretty good, a few that are almost decent, and then there are ones that completely useless in PvE. I'd like to start off with the useless ones first.

Dragon's Pit: This was one of the first moves that got nerfed after Mystic's release. Because this move was just an unprotected area of denial trap you used to be able to quickly get out of her animation almost instantly. You can debate about it's current effectiveness in PvP, but in PvE it's slow uncancellable animation is an outdated nerf that needs to be reverted. And even if it was reverted, the damage and number of hits would still need to be reworked to be effective in low end and high end PvE.  

Dragon's Rip: Like Dragon's Pit the damage needs to be reworked. Because of it's slow animation and the long cooldown of Waveorb it would probably be better if it is changed to a 3shard skill because it's unlikely you could fit it into her skill rotation if it was just another one of her moderate damage attacks.

Tranquility: It's easy to forget this move even exists because you will never you it. 40s cooldown for 3shards and some WP, when at any moment you can just do Rapid Stream into Tidal burst and get the same effect (and it doesn't even flow into crouching wolf). It would be better to make this move flow into crouching wolf and change cooldown to 8s or 10s. 

Now for the "almost decent" moves.

Raging Wind: 13s cooldown is too much. It has no cc and no protection and the damage by itself is not high. This move should be at least useable on cooldown and maybe have it's crit rate or damage reduced during cooldown. It's an important move since it helps recharge shards, so it needs to be always useable per pack because you need 3 shards for crouching wolf speed buff and 3shards for the main damage combo. If not then at least make it 6s cooldown since it's usually paired with Dragon Strike (6s).

Rapid Stream: The damage is just too low especially when you see that Tidal Burst and builds up more shards and Rising Dragon has much better AoE for DP debuff. It's a massive loss of DPS just for prebuffing and debuffing. It's counterintuitive.  It should at least have it's core skill switched with CC's and let it have forward guard by default. As it is now it's just another PvP centric move that has little use outside of it. 

Gushing Waters: You can argue this is legitamately a good move, but try figuring out why it's a 7s cooldown when you mainly use it after Spiral Torpedo (5s). Without Gushing Waters' near instant animation flow after Spiral Torpedo, Spiral Torpedo would just be another slow low DPS counterintuitive prebuff move in PvE. 

Overall awk Mystic is a viable class but with a few strange moves and properties that will scare people away from ever trying it, especially when succ Mystic exists and is better in both PvP and PvE. Any work and effort the devs put into her rework is wasted when people can make a superficial look at it's flaws and instantly judge "why play this over succ Mystic".
