Pretty sure it's too far into this event now for me to make that up unless I get at least half the slayers, which at a chance of 1 per day (and just a chance) is not going to happen (I got the 30-day eGacha ticket, used it and got an SR, used a card reveal and got a non-slayer out of it). As I said, when things like that happen (or I spend the achievement gacha tickets from other games such as Angelic Saga and just get a duplicate copy of a commonly-available rare, as also happened yesterday) it just... makes me wonder why anyone would want to gamble like that. I saw someone on Facebook post that they spent $200 on AS gachas and didn't get a single one of the new cards.

Still, while it's too late for this event, it is something that would be worthwhile considering to stock up on for a future event (when you can turn them all in right at the start). Another good point in that sense, but I'm still wary due to the RNG factor.
