you are reasonable and have a good spirit :)
but I believe there are a few things you are not grasping:
1: in market dynamics we study value proposition. because an offer has similarities with other offers, it doesn't mean it's going for the same value proposition. Although valorant may be similar to cs, it's not aiming to deliver the same value proposition. Cs has an unique value proposition that have been tested and strengthened throughout the years. Only way such a beloved unique value can be undermined is by substitute offers, which is not the case at all, even though there are similarities.
2: maybe you haven't been around for so long, I have played cs since the beginning 2 decades ago. We had A LOT of problems throughout those years, and it never died - to the contrary, it's still growing wildly after 20 years. Do you know of any other multiplayer game that has achieved something like that? Most game products die very fast in comparison. So the problems are already "coming up time and time again". Only reason you feel so much 'hate' or 'panic' for this problems and fear of bad effects is because you too madly love cs. Which is the primary reason it's not at risk :)
3. people won't move away from cs unless there's a better substitute. It's not about anticheat and 128 tick, you are only scratching surface here. There's MUCH MORE to csgo both ingame and on ecossystem supporting it. In order to directly compete with cs, a new entrant would have to offer AT LEAST the all the same attributes, or better versions of them, and the likelihood for that from Riot with Valorant is ZERO.
4. these said problems within csgo are not as big as you make them sound, in reality. just check data
5. the reason I do not encounter cheaters is not luck. it has been a SERIOUS problem in the past, but it's much better now. I don't encounter them because I'm a good player, always respectful, never cheated, 16yo steam account, thousands of games, few reports, never lobbied with cheaters/griefers. If you have a good behavior in no time you will be playing awesome games like I do. You have no clue how it was to play 1.6 on IRC scrims. That was really cheat paradise, no matchmaking, etc etc etc and nevertheless it didn't kill cs even though it was 100x worst than today
:) have a great time and keep safe too
