As someone who have years in arknights gacha can say it is good. The biggest joke is that Hypergryph company behind Arknights creation is a music company and then Gacha and etc. So music direction is always great in all PV for events or character songs. I would say they first season bit lore heavy and is worst in terms of story, mostly rough start of gacha story that was revised. Second season and Third is where the peak of AK storytelling… There is a lot to cover storywise so 3rd season won’t end Chapter one (out of 2 which ending soon on CN, global is behind as typical gacha but by 6 months only).
So moving away my bias as gamer and purely on anime. I would say it’s decent and good if you can close your eyes on some aspects. The minus are typical anime tropes of child protagonist, amnesiac main character, child is face of the organization. Pluses would be that it is really grounded world building with big premise on suffering of incurable disease and treatment of poor/ill/different race and even specific racism against one race.
So give it a thought, if you enjoyed a bit first season then second will be even better.
Yeah I would agree that for casual conversation Discord overtook for me. I was lurking r/warframe and after losing pc capable running game started gacha and discussed on r/Arknights. So with api fiasco I left Reddit and tried Mastodon… have account and check it out but there is no activity on #arknights , joined discord server for R/Arknights that was made during blackout and still going strong. Like I got better of R/Arknights and not on Reddit. People some use Reddit, some silently, some like me abandoned and even people who never used Reddit joined. Moderating m/Arknights on Kbin but with Kbin dev having unlucky strike and generally hopping he have health to both have normalcy and work on Kbin. So without proper mod tools and some broken features (like webp not displaying, where microblogs from Misskey converts to webp to consolidate space) and some other little wants that I would propose if I knew there would be implemented.
Using Misskey.io before it closed registration to Japanese only (happens when everyone was leaving twitter for Musk dumb thing he implemented). With Misskey at least found artists and players for Arknights but as it is Japanese instance, they only thing I can do is share art so #arknights tag weren’t dead on Mastodon.social .
So TL DR left Reddit, joined sub Reddit discord server which is where I spend most of my leisure time, using Mastodon for news, Kbin for moderation (but no one visits, at least no spam as I clean up) and news , Misskey for fan art.
