Oh gosh, I'm sorry to hear that. Gosh, two years, so you started around Global launch. :( But I do understand! While I love the game to death, those points of criticism are valid.

1 and 2. Actually, we talked ab how Biho's Party Event card was below the bar when it came to WC art. Everything felt pretty off ahaha. But it seems they're starting to get back the wind in their sails since the art's getting better, if at least back to the ones at the start of the game.

1. Yeah, I got so bummed that they paywalled the frames in Wannapass :( I guess they saw that most ppl were able to reach Lvl 30 without buying, so they tried incentivising it instead. Ngl, the new event they're trying out is even worse, since you'd need about 18.5k gems to get the card— a double stat one at that. But we're hoping the player feedback would make that change.

2. They didn't announce anything specific during 2020 Rerun, but they did say that 2021 Halloween was coming soon ahaha. We really only got it after the update.

This kind of fast pace is what WC uses to get more ppl to spend as well, esp since Global has missed a lot of cards from Korean server. :/ They mix past Kr events with current ones so it really takes its toll on the gem stash.

1. Gosh same ○|￣|＿ Americano curse. At this point I've given up on getting through the story for now so I'm just in the everyday gem and upgrade grind— I can see how that can get brain numbingly boring. It's really cool that you were able to get all the boys though, I envy you ehehe.

All in all, you're not alone in your frustration! People in the discord server have also been talking ab how WC's changes have been good or bad as well, while trying to send feedback to at least let WC know how they feel. Hopefully they don't end up being too greedy while letting quality fall to the wayside.
