I get the same feeling as I did when Bungie got all excited over Reach's ranking system: "why fix what isn't broken?"
H3's system worked just fine as it was. The only issue was deranking/boosting, the first of which can be fixed with Reach's ban system and the second of which can be fixed by limiting the number of games which trueskill counts towards (for example, last 500 or so).
But in any case, my point isn't to argue about the old system, but rather to point out that if you actually want people to care about your idea, you first have to tell them why it's necessary.
Probably more than 80% of people will read the first sentence and think, "waste of time, just use H3 or H2 system. Keep it simple."
If you expect a serious response, you should give a reason for people to want to read it in the first place. Large reports generally start out with a problem statement for a reason.
Just some constructive feedback which I hope you consider, rather than simply get offended that someone doesn't agree.
Secondly, I completely disagree with ranks being global. Why should I be matched up with a SWAT 50 when I'm playing TS or MLG?
It's a very different skillset and SWAT-only generals are 99% garbage.
Likewise, even though I have a LW50/TS48, I have absolutely NO illusions that I would be able to keep up in snipers. Hell, it wouldn't even be fun because I know the snipers kids would wreck me. I'd be more like a colonel in there...
