I’ve decided to create a poll to see what people think on the idea of restricting the duplicates.
My arguments for this:
Allowing a cap on duplicates would level the playing field more than it is currently. Egg timers who have 50 Frillzeon (or some other type) won’t be able to use all of those in missions, for example. The same applies to people who use way too many Omegawyrms, or monsters they timed from mission eggs, or people who use tons of the same type with an ocarina.
A cap on duplicates would allow fair competition in the infinite dungeon - some people can’t compete with people with many duplicates, and some don’t wish to play this way.
For the somewhat heated discussion about this, see this topic. It shows both sides of the argument.
