Anyone ever felt that there getting worse at bjj

What about instances when just one part of your game is suffering. It seems like my sweeps and guard passing is steadily improving but my submission game seems to be regressing.

Any advice for shoring up your submission game? Should I concentrate on a few submissions and try to master them or perhaps my training partners are used to my subs and I need to add new subs to my game. Is there a certain way of thinking submission specialists have compared to guys who constantly think about positioning first and only get subs when they fall in your lap?

I feel like I am also in a similar situation. I spent an extended time only training at an MMA school and not a BJJ school. I started training at a BJJ school and I've found my top game and guard passing has gotten really strong but I struggle a lot getting things done on from the bottom of guard. I also struggle getting out of mount and side control.
