Wonder Trade Idea:
I just got to thinking that PokeMMO doesn't have a Wonder Trade feature. It probably would have to be restricted to a certain amount of badges (obviously 4+ obtained total), and maybe certain Pokemon level restrictions. Basically it'd work like the Gen 7 and 8, but also have a rare random chance to get a special "prize" Pokemon. It could be a shiny or comp ready, I'm not 100% sure how that'd be taken but it's an idea to make the Wonder Trade feature a bit more unique.
Pokeball Idea:
Second idea is more a QoL implementation, just to make it easier for catching things and is rather self explanatory.
