Combine the chances together

[MicroBoss]

i know alot of people would like the chances of the giveaway to be combined, i think i know why it isn't (the chances would decrease 2x faster) but this way one server wont be full and then no one wants to join the 2nd they are just wait until someone leave. but this way people will join both servers and both server will be in usage.

i was thinking either the chances would decrease each map depending if the other server switched maps or after map change if other server switches it would add +2.5 on chance decrease.
