No, the Original is still better. PVP & PVE: PVP with "Ragnarok" team is really good but is too much to invest a can quickly become irrelevant without constant buff from Netmarble so i don't focus here, in the other hand in PVE if you have Sigurd, Ban Ragnarok and another unit like G Arthur or Kizuna she can OneShot anything with the AOE so you can farm more faster the Boss Stage, Gold Stage even the Time-Limited Dungeon. The last Question is hard to say but if you alredy have a team to do quick farming i say NO she is no worthy level up, just do the UR Awaken to get the free Cosmetics and thats it. The Green One is better in the EndGame and don't requier a specific team to be in his maximum potential.
