some anti red cats, I mean seriously, call centre cat, bean cats AND catley for anti red knockback? these units all powercreep eachother and without any sort of particular unique roles the game just gets clogged with cats that aren't useless, but then they're outclassed easily.
so either cut down on the powercreeped cats or:
give cats like bean or CCC barrier breaker or anti relic abilities. bean needs it the most. CCC serves a fair role that isn't AS easily outclassed but it wears off quickly. or make an entirely new enemy type in the future which can help give buffs to such cats, in fact, cats are already gaining buffs for barrier breaker and anti relic.
one thing to remember though is that players who do have CCC will be stuck with a useless cat for a long time and honestly should be strong enough to have vacation queen and CCC on the month that it's available, considering how long it can take to get to that endgame point, it would be pretty weird to have spent that much time and experience playing and then not have CCC. and besides, if they're good enough to beat the game so early they're not even in time for the CCC event then the chances are they're so strong that having it wouldn't change much
