What do you miss about KPOP "back in the day"?

I have been a KPOP fan since 2010. BIGBANG got me into KPOP when I randomly found one of their songs on Youtube,, along with B.A.P (I was so happy when 4 of the members came back recently!!), and I was a pre-debut ARMY. My interest tapered off a little when BTS started focusing on America. Not to mention MBLAQ, BLOCK B and more. These days I'm mostly into ATEEZ or some random group songs here and there. I have seen B.A.P twice, BTS 3 times in 2014 x2 (Red Bullet Tour) and in 2017 (The Wings Tour) and then they didn't come back to Australia. My first concert was CNBLUE in 2014 and I saw BIGBANG in 2015 I believe it was. :')

I'm feeling kind of nostalgic today so I want to ask long-term KPOP fans - What do you miss about KPOP back in the day, and how do you think it has changed? Do you think it has changed for the good or bad and why? :) Who were/are your favourite groups??
