At first, the new ranking system was almost infuriating to me. The fact that this came up in the first place is a bit confusing -- I wasn't mad about the change, but the fact that this issue ever came up in the first place.
It seemed that there must be a much better way to handle the rank curve distribution than what was put in place. Maybe this is in part due to the rank adjustments made after winning games that you queued with a cheater, or lost against a cheater, or the growing population of active players. While I certainly can't think of a better solution myself, given so many factors that are difficult to predict and for the most part out of a coder's controller, like hackers, smurfs, and derankers, to anyone faced with the dismay of losing two ranks after two losses, the first thing that will come to their mind is "why did this have to happen in the first place?" Regardless of whether or not the issue is as simple as it seems.
So I don't think that people are as mad about the fact that they are losing ranks, but rather that developers would be in such a situation that the image next to their name on the home screen, one they coveted so much as "infallible" proof of their improvement and skill in the game, would have to be wrenched from their grip. Especially when Counter-Strike is such a difficult game to learn, and improve at, given its many game mechanics that need to blend together perfectly to become a great player, it's hard for people to think that it wasn't for naught after they didn't have their previous rank as proof of it.
In essence, I had improved so much in my journey from Silver II to my peak, SMFC, and didn't think my brand new DMG rank brought it justice.
But, having taken the time to truly think about while writing this comment, I took a step back and really thought about why I thought this change was such a big deal. My skill in the game couldn't be gauged by an image. The reason people use their ranks to gauge their skill is because improvement in CS takes time, enough so that you can barely even notice that you're improving, just like you don't recognize that you had grown a few inches until actually being measured.
Realizing this, I looked back to my Youtube channel, where I had uploaded DMs, clutches, and random clips for more than a year. I looked back to my proudest moment from Silver, and then to the latest clip of a DM I had uploaded less than a month ago. And then, I realized, that I should be proud of how much better I had become, and not of the rank displayed next to my name. It's easy to get wrapped up in the fact that rank directly equates to skill, because people judge you based upon it. You want to queue with a new player? First thing they'll ask is your rank. You meet someone in real life who plays CS, and you realize they're LEM and you're only Gold Nova? It's demoralizing, and can fuel your want to improve even more.
So, for all who are frustrated with their rank change, I suggest two things for you:
1) Benchmark yourself. Record your clutches, DMs, and fragvids. Think of them like a time capsule, but for Counter-Strike. You'll look back at your past clutches, laugh at how you ran out of B Tunnels with a nade primed after not checking any corners, and realize how far you've come.
2) Detach yourself from your rank. Play for fun. Your rank shouldn't dictate the way you want to play, but never purposely try to ruin other's fun by deranking. To clarify, if you love using the nova, and want to spend the rest of your days with a nova in hand, striking utter, close-ranged, terror into the hearts of CTs and Ts alike, feel free to do so. Your rank will adjust to the point where you will not be hindering your team by doing so, even if they do get mad at you. If people mock you for your rank, take no heed of it. Use it as a reason to improve, then do so, and throw it back in their face (assuming you are as competitive as I am). That LEM I met in real life when I was a Gold Nova prompted me to spend nearly a month only DMing, and I challenged him to a 1v1 after he dismissed something I had recommended since "a nova told it to him." I won, and damn, was that satisfying.
