>>47895379For me it needs to be clear enough on its own but at the same time be capable of being wide enough into multiple different things.
The basic elements are based because of that, you can clearly tell them apart and they can fit into infinite themes.
Ghost while more complex, it too because it can get very creative while you still knowing what Ghost means, Fairy too.
I hate Rock because the idea of minerals being a type is just boring and it ends up being the same concept over and over again, which is redundant.
It would be better if Rock got merged into Ground, in a similar way how Flying unites both Flying creatures and creatures that control air.
