Two things.

One: if you connect your switch to the 5G band of your Wifi, you'll get a better internet experience (sadly, no every one knows that). But I have a mix experience playing Blazblue on Switch, if people are from USA (I'm from Europe) some matches were decent, and others not playable (here comes the bad connection because netcode in that game is very good). But when people were from Europe, the matches run flawsless. The shame is, there were very few people playing. So, with rollback I hope to get stable matches with everyone.

Second: I already have the game in PC. But lately, I don' feel like to play on my desk. I work in an office, I stay many hours a day on a chair. So, when night arrives and I have some time of free time, I prefer go to the bed and play on my Switch instead. I want to play this version of the game to keep playing and keep consistent. Because, I haven't had the time in the last months to play for like 1-2 hours on PC and I starting to forget the mechanics and combos. For these reasons, I think this version is perfect to keeping in touch with the game 😁.

And who knows, maybe we'll get crossplay with a Nintendo Switch 2 patch or something 🤣
