ABI DON'T CHANGE! YOU ARE PERFECT JUST THE WAY YOU ARE! 
That I do not agree with. Obviously she knows she was wrong in a lot of ways and by telling her not to change it's like asking her to continue to be mean/rude. I think everyone needs to grow up at some point in life and I'm glad Abi realized it. <3
One of the things people seemed to hate most about her is she was honest to a fault. She said what was on her mind without a filter. Personally, I don't see that as a bad thing, but I guess I must be the only one.
There's nothing wrong about being honest, don't get me wrong. But Abi was really rude/obnoxious at time. It is a BAD THING to be rude and obnoxious and if you don't agree with it... erm, ok. 
Obviously being rude is not good, but I think it was exaggerated imo.
Best example of what I am saying - Abi saying to Skupin that "you are an idiot, you are a moron" at the Final Five. It was completely true and completely honest - it could have been delivered more delicately but I still like the honesty.
