I know its a big part of the game, you say that people like it yes but cs go is not like chess, chess is only about strategy, I can see your point if you like the awp because of the strategic side of the game, but cs go is more than just a strategy and it requires good aim also as we all know, now the AWP makes the quick killing and hiding part easier and not only that:
-it puts other players at disadvantage at a lot of places on the map(I see that is alright for you because of the strategy involved and I see that point of view),
-it brings more luck to the game - when you kill with 1 shot bodyshot often the kills are through smokes and flashes as the target is bigger and you need to shoot once, other weapons can do that too but not to the same extent, also it's just faster and easier to have a quick kill with it
-makes the game less enjoyable to watch - now cs go is an esport and it needs to be exciting for viewers, otherwise sooner or later it's going to die, people get excited by the strategy part AND the aiming part of the game, after a good awp nerf there are still going to be strats with the AWP, just LESS rounds, the game will become better to watch with a lot different kind of rounds, and lets be real - nerfing the awp does not mean rush everywhere no thinking, it's just going to be different and more fast paced but also not TOO much, that is whats going to keep the viewer, it just needs a nerf that will still make it viable, you won't know if the other team has an AWP and where it is, players will now have to do MORE things (talking mainly about the awpers) and still buy an AWP on rounds/maps that it could really help because of the range or a certain strat, not be used in every map every round just because the team has the money
That's what Im trying to say and it wont hurt when you try, then you can change more, even just the changes keep the playerbase alive, imagine valve didn't update anything ever, the game would be dead by now - it just has to be not too much like other games and it's all good for everyone.
