About rep system...

Sadly, history has shown that you are not correct in your thought. People can raise their rep just by playing fair and being sporting in the way they play. If your idea was put in place, they would know that their rep would return to normal in time and that
they could get away with bad behavior. But if you think this is a really good idea, you could post in this section of the forums:
http://xbox.uservoice.com/ to have your idea considered.

So basically this new system is going to make it difficult for me to earn the bad player rating?

As soon as the cry baby exploiting abusers get their grubby hands on it good players REP will be wrongly reported.

Like Owen said, all it will take is beating a few clans or groups of sore losers and boom, broken reputation system.

"So, how are we doing this? We are simplifying the mechanism for Xbox One –
moving from a survey option to more direct feedback, including
things like “block” or “mute player” actions into the feedback model.
The new model will take all of the feedback from a player’s online flow, put it in the system with a crazy algorithm we created and validated with an MSR PhD to make sure things are fair for everyone.

.

Ultimately, your reputation score will determine which category you are assigned – "Green = Good Player," "Yellow = Needs Improvement" or "Red = Avoid Me." Looking at someone’s gamer card you’ll be able to quickly see their reputation. And, your reputation
score is ultimately up to you. The more hours you play online without being a jerk, the better your reputation will be; similar to the more hours you drive without an accident, the better your driving record and insurance
rates will be. Most players will have good reputations and be seen as a “Good Player.”
The algorithm is looking to identify players that are repeatedly disruptive on Xbox Live. We’ll identify those players with a lower reputation score and in the worse cases they will earn the “Avoid Me” reputation.
Before a player ends up with the “Avoid Me” reputation level we will have sent many different alerts to the “Needs Improvement” player reminding them how their social gaming conduct is affecting lots of other gamers.

.

The algorithm is sophisticated and won’t penalize you for a few bad reports.
Even good players might receive a few player feedback reports each month and that is OK.
The algorithm weighs the data collected so if a dozen people suddenly reporting a single user, the system will look at a variety of factors before docking their reputation.
We’ll verify if those people actually played in an online game with the person reported – if not, all of those player’s feedback won’t matter as much as a single person who spent 15 minutes playing with the reported person.
The system also looks at the reputation of the person reporting and the alleged offender, frequency of reports from a single user and a number of other factors.

.

This system will continue to evolve and get better as we track the feedback we get from players and titles, plus add more consequences for the jerks. It also helps us match you with other gamers like you. Of course, the system will be as good as you make
it, so all you need to do is report the players that are abusive, cheating or causing mayhem and their reputation will reflect that. Thank you for helping us continue to make Xbox Live a place we all love.
Our team and I built this for all of you and we hope you like it!"

I thought there was a video I had seen or an article that went into more depth, but I'm having trouble locating it.

Alot of people who legitly play will be unfairly labeled "Avoid Me" mainly because there will obviously be tons of people who will abuse the system. Why Microsoft cannot simply set the options in the rep system to a simple yes I want to play with this person
again or a no is just leaving me speechless again. Complicating everything is just setting up an impending disaster and another tool for trolls.
