I would rather have reputations removed and replaced with another form of progression than have them simplified to the point where they have no lore basis, no roleplay value, and are simply bars to fill up.
Making them completely BoA would be a move towards this in my opinion.
I also believe that if you want to have another character that has just as much stuff as your main, you should have to do at least ~75% of the work you did on your main to get to that point. An alt should be another character and offer you more things you need to do to progress. If you start an alt and just have 100% of everything, that's removing a lot of the gameplay of having an alt, and the reason people make alts in the first place. Generally because they are bored and want more to do. If you remove all of the progression from alts, what will rolling another character add to your experience besides a different rotation to do?
