As a player who often has to reserve an entire team of class slots for a highlander game, I find it a bit tedious to click nine times to reserve every single slot.
I think adding two boxes for each of teams that would instantly tick all the classes to be reserved on that team can be a nice addition that takes up very little space and lowers the amount of clicks required to properly set up a reserved lobby.
I'm sure a lot of growing teams will benefit from this, as this shortens the amount of time required to create lobby itself so it can start filling faster.
Thanks.
