It’s a very good thing.
Taking the mobile gatcha game I play, there is a Global and a Japanese version of it.
The Japanese version always has their rates displayed, because of the law forcing them. But not on the Global version.
A lot of the whales playing on the Global version have come to suspect that the rates are deliberately lower on the Global version. A person even managed to datamine the rates and confirmed this suspicion even further.
This is why having the rates displayed, for us Global players, is a really good thing. Either Bandai goes ahead and shows that the rate are lower than JP, creating community backlash. OR, they increase the drop rates on the Global version before the release of the public drop rates, making both versions equal.
Either way, this is a win-win situation.
