you can catch up fairly quickly, there's more ways to get rainbow and golden prinnies and they added some QoLs like equipment alchemy pity or innocent boosting being much more streamlined. The usual flow every month is:
>event, with its own story and hard stages you can unlock every day with keys, and of course the usual event shop
>raid, which is faster to clear compared to global since it's now its own thing with its own stages, a lot of goodies and a little epilogue for the event preceding it
>etna defense, for etna points
>sugoroku, a game board where you earn dice by clearing stages and claiming them daily, there's 2 sides for the stages and they all require you to use specific characters based on their weapon forte. This gamemode also always comes with a banner that contains 2 rerun units, usually getting buffed, 1 for each side, and pity is at 10 multis
New units are usually pretty busted, but you better look them up or ask in here before pulling if you're actively looking for a specific role and not a favorite character
