After thinking about it more. They need to change these 4 skills:

Feint
Disembowel
Ring of Talons
Doom Spike

My suggestions:

Feint should swap with Disembowel and give the piercing debuff. This way if you run into a monster that you cannot get behind, demon wall, it would not screw us over too much.

Disembowel gives the slow instead of Feint. Validates actually having slow on the mob granted it doesn't naturally resist.

Ring of Talons should give a weaker AoE piercing debuff or possibly another debuff. IF it gives the piercing debuff the potency should be lowered.

Doom Spike still needs to be buffed by 10-20 potency, have potentially less tp drain, or give a mini dot. Anything really to make it a "different" kind of AoE when compared to RoT (YES, I know one is a line and another is a circle but in most fights you do AoE it is a trivial matter lol)
