>>44037172The biggest things I would do is:
Don't use "non" elements like Bug, Ghost, Fairy, and Dragon. It's just bloat.
Get rid of the Wind element or equivalent. Wind is always a stretch when it comes to rationalizing their strengths and weaknesses. You could say that Wind beats Earth because of erosion and height advantage, but you could also just as easily say that Earth would be strong against Wind due to its weight and resilience against erosion. Being blasted or sliced by Wind just feels typeless; It's a force that doesn't really have any special or crazy properties. Plus you can always attribute another element to certain Wind-based attacks, such as blasts of hot or cold air, dust, smog, pollen, hurricanes, etc. and the few attacks that don't fit any other element would just be typeless.
Don't have elements that are strong against themselves and don't have a circle of only 2 elements that are strong against each other (Popular example being Light and Dark). There should always be at least 3 in a circle so that each element has a both weakness and a resistance (other than typeless).
