Random question, but I'd be interested to hear your biggest DV hot take.
You might expect me to say something about accessory quality control rules, but no! I just really want a fighting system.
I know the Devs want zero violence. But just re-skinning a pokemon-style battle system (like FR and FV have) into something harmless would be like zero extra effort.
For crying out loud, make it a cook-off! Your WH or pet cooks dishes every round, which the opponent has to counter with dishes of their own. HP bars can be crowd appeal/popularity, weapon equips can be recipes for the dishes you make in battle. Infinitely scaleable since coming up with new foods is about as easy as coming up with new weapons.
Wanna tie it into current systems? Stat requirements for equipping certain recipes. Pets can help with the cooking. Generally just use your WH stats to boost the success of your equipped recipes. Cook-off against the NPCs as bosses to win items from or spins in their shop. All of them already have a food associated with them!!
Potions/usable items? Present a pre-made Conecake or NPC food in a round to recover some popularity or for some other effect. Eat a stat food to temporarily raise your stats for the battle (raising your success with certain recipes).
It really, really would be fun to have something engaging to do on the site. Something that doesn't have a daily cap, pays out fairly and isn't slow af. Better recipes/equips would be a longer-term goal while finding creative builds to beat bosses could be a short-term one. And you would have a sort of money sink built in because of the buffs from consumable items!
Please Devs, if you hear me, you have my full permission to use any part of this. Just make the site less boring!
