My personal opinion is that I'm not really fussed about my rank and it doesn't incentive me to play. I just enjoy PTFOing and supporting my team to the best of my (sometimes lacking) abilities. That's enough for me usually.
Obviously I'm not expecting my opinion to match everyone else, and there is arguably merit in refining the existing system for people who do focus on and enjoy ranking up (E.G. lowering it from S999 to make it less of a grind), but it's just not something I focus on myself.
In my honest opinion BF2 had the best ranking system along with awards and such. The actually had meaning behind them when earning them.
