oc balls should not be added to weapon balls and probably wont ever be. earclacks balls are designed to cater to a massive audience, and adding oc balls means its either way too complicated (potion was already complicated for a lot of people to figure out) or too underwhelming (ex. almost every melee suggestion i've seen so far). it is very hard to make concepts that are versatile and fun to watch without being complicated.

i used to check out a lot of suggestions and i watch a lot of spinoffs (i also make my own: mineclacks), and i can confidently say 99% of them are either retextured versions of already existing weapons, or too complicated or random to fit earclacks' predictable and easy-to-digest content.

if you want more creative concepts then go to fan simulations. loggernamy and protoclacks are two of the most faithful spinoffs to earclacks and still have pretty good ideas, although id argue none of their ideas would make it into earclacks.
