Hello,
In my opinion there should be atleast a general way to change nature for your normal pokemons too (not talking about some tournament reward).
Cause many times I see people catch 25+ iv almostly godly pokemons but the sync fails and its totally a waste.
I myself have caught so many 20+ which is just useless cuz of wrong nature.
U can make the price relatively high for this type of reroll from the nature reroll for legendaries , so that people would only buy it if its really worth it to change.
Hopping that staff may consider this.
Thank you
