Someone's probably already mentioned this before but I haven't read any posts so who cares:
When TXT debuted and continued to have comebacks for a year or two(?) it was only BigHit. It was BTS and TXT. The label could focus on each team separately and actually devote and spend time on each group. Giving them such intricate/detailed concepts, lore, visuals, etc. They were basically special and their music supported those concepts and you could tell that people spent time and effort in their comebacks. But nowadays? When Hybe was established, having multiple labels and so many groups debuting/transferred, of course it's gonna be difficult. Even if they hire as many staff, managers, etc as possible - it's not gonna be the same anymore. They have to focus on so many groups, while also trying not to give repeated or recycled concepts, visuals, etc. This is what I think at least... Idk there are just so many factors to it. And this is IF they ''fell off'' or lagged behind. But I personally do think that I found TXT way more unique/special with their interesting concepts and music before, than nowadays. Last time I truly was excited for a comeback was probably Love song/IKILY.
Edit: But something that's kinda strange, is that apparently, TXT is as big as ever? At least in some parts of the world such as Korea and the US?
