So i was playing on deathrun server today, and i realized that the map lasts for 30 mins, but when u play a deathrun map even if it's a good map u get bored from it after 15 mins . Even if there is the rtv system; it does not always work (what i mean here is that not all the players will type rtv for a reason).
So what i suggest is to replace the time by "Rounds", so when the map starts a vote pop up, and u can choose to play either 7,10 or 17 rounds (for example). With that if people fail a lot in a map (and obviously they will get bored from that map), it will end fast. that way people will not need to try and get the rtv or to wait for the 30 mins to pass anymore.
Hope u like the idea

Notice that a lot of a good deathrun servers use it.
Peace !
