1. I wanna know which is the best PVE class for dungeon and bossing currently?
2. Additionally, what kind of IM set do they need and also the equipment that the classes need?
3. If possible, list out for me or drop a link for me in this comment.
1. I would say Destroyer. I dont have a Ninja but Destroyer does not need a Paladin/Clock for being useful .
High Damage
2. for PVE i would mix it: Best Ulti Glove, Shoe and Back, God Bottom + Shoulder, Gift box Hat and Dark Magician back + Top if you have the budget...
If not i could give u an cheaper option but this would be some of the bests.
3. I dont have a link but u need CritDamage, CritRate, MovementSpeed and AttackSpeed Cap or nearly Cap for dealing the most damage. + for the new Dungeon u need 50k+ HP and at least 20k Deff.
