I read the quick start guide and original newfag guide but neither gives advice on how much of your starting budget to spend on supports vs characters. I've played grub though, if supports are your grid/summons equivalent then I assume the meta is to only care about them and not characters, but I've never been a metafag or an oktowife so I'd much rather spend my gems getting more horsepussies than dupes of cards that do nothing but raise stats.

are there any grindable cards or shit from events that dont come from the gacha like in grub or are you required to choose between horsepussy and stats?
