Just gonna break it up into paragraphs for each paragraph to respond.
1) Shroud was a pub god. the guy in comp was average, but when he went into pub matches, he would make a highlight every match multiple times. However, what people forget. Most pros can do this, but they just wernt as marketed as shroud was back in the glory days of him being posted on the reddit page every day.
I think it was a few weeks ago. Saw a few val players just chilling and going back to cs for a bit, just chilling in fpl and faceit. Could still clearly see how good they were compared to the other people. Again, it's similar to shroud in pubs. They still have the experience of 5/10/15k hours in the game, and it does show.
2) The reason NA cs "died" after val came out, isn't that players swapped. It's that no large org was investing in the scene. People didn't leave the scene because they wernt signed to top tier orgs. They left because valve left them in shambled after covid hit. Orgs pulled out, events stopped, and no money was being pumped around. Then val came along and took what potential prospects the scene had. Which imo were players that cold compete at higher levels (Xeppa, Leaf, s0m, wardell, etc). They were all young enough and huge potential prospects from the scene.
I will agree that the scene isn't dead. It's rebuilding, much like you said. the scene will rebuild it self. It's just at the point if newer players will go to CS to try to make a future, or to valorant.
3) with val being a trend game. I see it started as a trend, but getting more cemented in what it is. Even fortnite right now gets good viewership. Not what it was, but far more stable than other games. Val I can see being on the same track. Getting a table viewership, much like how league does.
Cs is by far a titan in esports with viewership, but other than that. It was never a competing game on twitch for content creators. On youtube, it's a different story. CS is just a really odd game for things such as streaming, etc. This might be because I wasn't there in it's peak for content creation. Just the past couple years I've been watching cs streams. It's always low until a large streamer carries the catagory, be it gAuLeS, s1mple, etc.
4) Tarik, I watch him here and there just because I find him funny. I tend to watch streams with the chat sidebarred so I dont see the random shit. him on val, or on cs. I feel he can compete on either. Dude was nuts on CS (unfortunate last few months on EG), and is by far insane on val(in terms of ranked, so hard to gauge where he is at). I'm not sure if he'll go back to competing. if he does, idm which game. Just thought he was insane.
5) I wish they added more mechanics. sitting in my ranked lobbies, I see people who are imm2/3 with god awful movement, but decent aim.
Just wish bhopping was a thing and counter strafing. I'd love more mechanics that involve jumping. Still love playing Cs and just making my way through mirage on mid window to short in the span of a couple jumps. I've failed it thousands of times, and succeeded with it. nothing in val gets that, unless I sit there using raze satchels to get around the map. they're the most fun I've had with movement that i've ever had on val.
