I think this event might be repetitive, so they need to updated a little just like they re-skined duel quest / duel a-thon with the Mini event Circuit.
A new face for it would be good. But the event was always nice, a bit old but good.
They actually just want us to focus more on pvp and no new dialogue in story mode. Look at mobile legend, PUBG and other indie games sitting at top 10 apps they don't have a single story event.
This is sad. I have friends who don't even pvp and just play for the story events and characters. Konami said in an interview a while back that they were planning to try a story mode for 5ds to start with. But it seems like now they just care about pushing new boxes and decks to try to get you to buy them for pvp. We could use a story mode and more creative pve.
Even i don't play pvp. I only care about unlocking characters pretty much. People play the same decks created in the very same fashion and gets boring going up against those who can't come up with a good deck themselves. I'm about to give up this game this year soon.
It has always been like this Brishawn, it will continue to be like this in the future too. If anything, the meta right now has the highest diversity of decks with quite a few being competitive at the top as opposed to just 2-4 decks in the past.
If you want higher diversity, don't promote out of platinum league. Everyone at legend is going for KOG, consistency = wins, so same decks are played.
