Assumed option 1: Leave the oathbreaking mechanic in the game, and try to fine-tune what triggers oath-breaking with patches, hot-fixes, etc., treating the specific complaints as 'bug reports' with the current system.
Assumed option 2: Remove the oathbreaking mechanic entirely, and replace it with oath-breaker as a subclass option chosen during character creation/leveling up.
I really hope Larian will be brave enough to try 1, and am perfectly willing to make reasonable allowances for it not being perfect given how hard it will be to reflect all the different tenets. Apart from any other reasons to prefer this over option 2, having to pick oathbreaker at CC would limit options for paladins who may start off intending to keep to the tenets of their oath but then come across a situation where the temptation to break it is too strong.
I don’t think it’s a matter of just fine-tuning and bug-fixing with patches, though. I’m very much hoping that what Larian have given us in EA is just an early proof-of-concept for discussion and they’re already intending to invest significantly more time and effort in oathkeeping/breaking for the full release
