Greetings great developers and players.
I have a serious complain about the oathbreaker subclass of paladins lore-wise to be specific. The oathbreaker is an evil class, you use necromancy, fear and despair in your enemies. You literally cooperate with dark forces. But the problem is that you could become an oathbreaker when you only break a code (oath). Breaking an oath is an unlawful (chaotic) action but not an evil action. But what if a paladin is forced to break an oath in order to do good and protect innocents and victims? It is extremely illogical that paladin to turn to the forces of evil (and use evil magic) because he had only broken his oath, only to do good!
Also even in Baldrus Gate 3 the Oathbreaker Knight that turns you into an Oathbreaker is supposed to be a good knight but unlawful one since in the dialogue he says that he could not see the darkness and corruption of his previous lord. That lord was assumed to be a tyrrant and when the oathbreaker knight killed him, he killed him for a good cause but indeed it was a chaotic action. So that oathbreaker knight was supposed to be neutral good or chaotic good, but NOT evil!
Futhermore the subclass description of the oathbreaker "you have broken your oath in pursuit of power and ambition. Only darkness remains to fuel you know" is also irrational since you might have broken your oath not for power, but for the common good or even accidentally (without your will)!
That oathbreaker class you created is in fact the "Blackguard" class, so to sum up I suggest to create another subclass the "blackguard" if the paladin causes evil actions and turns evil and the "oathbreaker" if the paladin ONLY breaks an oath. If that oath you broke had a connection with the common good then you simultaneously caused evil action and you become a fallen paladin (blackguard)
Also I give you some topics for food for thought about this complicated subclass:
