TYM is scrubier since MKX came out, they individualize each other, start illuminati chats and discords, hide tech and research among the "top class" and hardly share, align themselves as a team making rivalries less fun and boring since everyone is on the same team now, helpful content is hard to find, a bunch of combo videos with jump in starters are posted all the time some of them are not even practical, start guides without having researched the game, hate working together to put useful information out.
Right now, i think the mentality of TYM in general has gone pretty small after IGAU, and the biggest issue its that is contageous, every new comer in the community has a chance of either allienate against the forum, or become a dick themselves, catching the same habits and patterns because they don't have that top helpful players to guide them and explains things to them. Reason why you see lots of scrubity nowadays.
Top players and tournament players have become better over experience among the years to spot mistakes and brokeness, figure the meta and such in very short time of lifespan, but individualism imo is what is taking the breath away from TYM.
I've learned a lot coming to this site back in 2010/2011 TYM came out strong ever since, content sharing and technical discussions brought a lot of top players today pretty far in this community, some of them are even testers or working for NRS now, but that only happened because there was no individualism, everyone was willing to levelup as much as everyone was willing to play to win.
