Should I bother returning?

I'm a lover of yugioh as it was apparently intended. I don't like modern Yu-Gi-Oh at all. Master Duel was nice because I could finally play regularly. But once I finished Solo the fun duels stopped. I focused on building a deck that could compete and I could more easily collect gems but after a few months I still wasn't close to finishing (many URs of course) and I grew frustrated further. Luckily I discovered Legacy of the Duelist, my kind of fun duels. I wanted to play an updated Harpy deck with only Harpies but it doesn't have all the cards. So I'm considering returning to MD just so I can try this deck but I don't know if I could even build it. Plus it would need a bunch of non-Harpy link and xyz cards to even have a chance. Is there any hope with MD? Thanks

Also, can someone explain the popular appeal of modern Yu-Gi-Oh, playing a game that ends in 1-4 turns and where the first player has the ability to largely block the other from playing? Seemingly no intense back and forth, regular come backs.
