My brief, less negative 2 scents on the situation as a current whale
Given all the doomposting I thought I'd share a bit of a different perspective.
I've spent around $250 USD/month on the game since launch and have every single character SSS. I can't really afford to double or triple that, so I won't be continuing that moving forward at least until the merger is complete. My solution is that I'll drop to buying the monthly passes and maybe a bundle or 2. I'll get every character to SS or SS3 instead of SSS and just accept that I can't SSS everyone anymore. Honestly...I kind of felt unfulfilled with the game to some extent and regretted getting everyone to SSS anyway. I feel like it made the game too easy, though I mainly spent to just support Kuro - never really cared about the leaderboards much.
In my opinion, dropping the entire game and missing out on its soundtrack, story and gameplay due to not being able to maintain a full SSS account is not worth it, though I do understand that it stings and the investment up to this point does feel invalidated in a way. Still, I think it's worth it to keep going. I also am happy for the merger because we won't have to wait a full year for Selena.
Just my thoughts, hopefully that's a bit more positive.
