Is Jhin/shen rework coming out in the patch this week? Is there even going to be a patch this week?

The answer to both your questions is no so where do I send the flowers for the funeral ? Jk patches come out every two weeks we got a patch last week there will be no patch this week in the patch you are waiting for is next week

28 January, something like that ( Not exactly, but we can expect the patch around 28 Since the last patch was 14 January and new patchs come out every 2 weeks.)
