Hi, i have a suggestion, since rerolling legendaries really cost a lot of pvp coins i suggest to make it a little bit easyer in this way...
Before, we coudln't lock ivs to reroll so what i suggest is that for every legendary, we can choose 1 stat to reroll let me explain better.
for example, pa 150 pvp coins to reroll only speed and the other ivs doesn't change, that would be 150 pvp coins for 1 stat only but at least if u get very close to a good one with the normal rerolls, u can do that. i hope u appriciate the idea. have fun
