Have you played it? If not, I hope you understand that people will try and overstate both the positives and negatives. I would tell people to wait a few patches, then pick the game up, since it is fun. The chance at having your character deleted (somehow), or encountering a progress stopping bug are pretty low. The only non viable build I've seen so far, at least during the Story, has been a pet build. Are there some stupidly broken passives that trivialize all content, yes, but using them us up to you since you can do all content without them. If you haven't played it, wait awhile if you have any interest in doing so.
