everyone acts like Oathbreaker is this terrible thing but it's an awesome class to play because you can be as morally grey as you want and you are still wicked powerful. I think because the way it's presented feels like a type of failure. Also because there are some glitchy bits with certain encounters - although switching to non-lethal damage negates all that. It's an easy work-around.
Personally, I don’t see becoming an Oathbreaker as a terrible thing, and like you I’m really excited by it. With a reasonable investment of time and effort from Larian (and some reasonable expectations on the part of players), I think this mechanic has the ability to add some fantastic depth to the experience of playing a paladin.
For me, it’s definitely the glitchiness that’s the problem rather than oath-breaking feeling like a failure. I actually think it feels quite cool, and the Oathbreaker Knight has a decently compelling presentation of its possible philosophical underpinning, making the Oathbreaker sound potentially like a principled independent thinker rather than an oblivious lackey of the status quo. In fact, as I might now be alluding to too much, my biggest problem with its implementation is not the times when we break our oaths when I think we shouldn’t (which I agree can be worked around relatively easily once you know what’s what) but the fact that the game either doesn’t give, or misses, opportunities to roleplay engaging oath-breaking stories like his.
