Pubg New Feature

Previously, I made a post about throwables glitch and how the delay is making players to not pick up enough grenades/smokes. Some people told that players would start spamming with nades and all. Few updates later,BOOM. They made it faster. But this feature directly comes from Chinese version (GFP)where you can throw nades without any delay.

Now,in the update 3.0,they changed the close combat meta entirely. The scope/peek delay is no longer in the game,so you can move+scope+ whatever you wanna do without any delay in character movement. Guess What, This feature is also in the chinese version (GFP) since the beginning.

My question is, If tencent bring features that already exists in chinese version 3 years ago, Why they didnt bring them sooner in the global version. Am not asking, just curious. Is it on purposes? Future updates are also gonna filled with things that are exists in china version
