As I recall, the only reason why I started playing TUS long time ago was Hysteria scheme. And for a good chunk of time, I've been picking Hysteria
all the time. I did not like most of the schemes that people picked (other than those which share artillery aspects like BnG), and I was kind of forced to play those in the past. The absolute worst experience for me was to play TTRR. Unlike other schemes, most people who pick TTRR are extremely proficient in it.
So yeah, I confirm that nowadays, one of the reasons why I wouldn't want to play TUS is exactly because I'd also need to play other schemes I don't like. The only reason why I've become better at other schemes is because I had to play them, but I wouldn't say I like them, though what you hate initially tends to transform into what you like, but that's more like Stockholm syndrome rather than love, when you try to understand and justify why people find those schemes enjoyable in the first place.
What if you played 4/8 of those schemes and had a great season, made the playoffs, although you refuse to play the other 4 schemes, does this mean you forfeit the Playoffs?
Yeah, sounds like I'd have to actually learn to play new schemes if I've never played them before. If that's the case, that does take a lot of dedication and willingness watching replays to learn new schemes. I'm not necessarily against MI's idea, but you have to be aware of the fact that people nowadays can't even concentrate watching a YouTube video for longer than 5 minutes, or even shorter (see TikTok videos).
