I've been on a mission to collect as many TT cards I can before SB drops, and I've been endlessly frustrated with most NPCs. Namely, NPCs with very short windows and TERRIBLE rules (Chaos/Plus+Same, etc.) I'm on maybe my 7-8th window for a few of these NPCs and they just drop nothing most of the wins, and when they do it's very very rarely the card I'm seeking. The last two NPCs took around 100 wins each to get a single card of their rarest drop. Something so steeped in RNG just isn't fun.
Perhaps the devs could look into spree bonuses? So if you win/draw multiple times in a row you get a bonus to drop percents? It could definitely help with the frustration. I just needed some feedback from others to see if the drop chances are that bad or could it be my RNG is just awful?
