Vincenzo Frogeiro here, this topic probably saying me. Ares did the good job at the emergency nerf because when the guardian and taekwon weapon launch together, TK really has Huge HP and damage and no need to repeat what is the damage again. After the emergency nerf, we found out the KIHOP party skill was really OP due to high rate and low rate server problem. As Ares said, the this skill unable to remove or nerf because this is passive skill. So GM team adjust again and reduce the TK HP and damage on the both ring again. I tested on both ring, blessed are fair enough for now since it's have 3 kick and all 3 kick duel with decent damage. I found out the problem on the cursed ring because cursed ring has just a kick which is tornado kick. So i think this is kinda weird because 3 kick on blessed ring and 1 kick on cursed ring. The tornado kick damage on cursed ring is lower than the blessed by 5k-8k depending on your str, attack and buff. I had no idea why this should be lower than the blessed ring? Since we spam tornado kick must come with another 2 kick to continue the combo. Well yeah TK ranker should know every kick without the ring probably just deal 2-5k on enemy. So the ring really important to boots on the kick.
My suggestion - can you boots cursed ring tornado kick a little bit higher than the 3 kick on blessed ring? You removed 70% damage on cursed ring but 30-50% on the blessed ring with 3 Kick. Weird.
+1 on the blessed ring, -1 on the cursed ring, +0 on the guardian.
FYI, i tested the damage with Ares in game and gave my opinion to him. I also have 3 ring complete ring.
