+1 , uu and random battle gonna make pvp more funny. i think rewards can be 100 pvp less than ou cause like u said , its more easy laddering cause u dont need to farm or train anyhting. But for my opinion , u could add uber pvp too, so funny too, and many pokes like ninja ash ,blaziken, traper wobufet ,legends like darkrai solgaleo, and more , could be usefull again, and gonna growth up the economy again.
