Gacha trash is common in every game, yeah, but it does feel ridiculous to give out evolution fodder in the gem gacha when there's a separate point gacha that, in theory, is much easier to roll. Obviously not right now, since buddy points aren't really properly implemented yet, but if you're going to rip off of PAD then you might as well rip off the system where evolution fodder only comes in the gacha you'd be rolling much more frequently.
