The deserter punishment system was introduced to . . . punish deserters. The preferred map system was introduced so that a player would not have a reason to leave a battle. However, this system does not provide 100% avoidance of disgusting maps, which the vast majority of players have thrown all the dislikes in the world.
If this system cannot work 100%, I propose to add the ability to leave a battle without penalties if a player get on the map that is on his dislike list.
This is actually a really good idea, I think it’d good to include the caveat that the desertion has to take place within the first minute or so of the game though.
From my experience the “dislike” future do not work - AT ALL. Its either not functional or is wonky as hell. Regardless its full on placebo right now.
If no one plays on disgusting maps, then developers will not have their heat maps to analyze and correct these maps.
Maybe they should test their maps? And just remove the most disgusting ones. I’m sure no one would be against completely removing the map with the conquest in the Ardennes and the map with caves in the Pacific Ocean. And for the big fans of this obscenity, leave these maps in custom matches.
good idea!
my experience so far: ca. half of the matches I get put into are ony my dislike list 
n= over 100
Dislike system is a good start but doesn’t account for presets and really varies in results depending on Time of day, server, faction - so needs some better enforcement, but I do like IF dislike on map choice reduced penalty only do round only…
