Currently, when you do a training grounds, a pre-defined map and rules are selected.
For example, if I want to do an elimination first, followed by a protect hostage, I have to change the settings every time.
This is a stressful process and inefficient.
So I think you should be able to freely choose the map and rules before starting the training ground.
My English is not native, so I'm sure it's poorly written, but I would appreciate it if you could refer to this as one of your opinions.
