Here is the solution for all of you who want to set certain amount of tickets. As you all know Dice only allows a percentage for the ticktes and in addition there are different base ticket amounts depending on the map and the gamemode type. So it is quite a pain in the ass if you want to set a fixed ticket count.
Fortunately here is a link to a list with all ticketcounts:-> Ticketcount list <-
And even better here is a ticketcount calculator:-> Ticketcount calculator <-
