No, the plugin gives you a certain amount of time to come back, it will say (example): p o p a y has left the game, if the player does not return within 10 minutes he will be banned. And ok, maybe 5 days ban is quite lengthy, banning for a few hours would be a good decision though, and if you're likely to be going off somewhere like work, going out with friends, then you shouldn't be mixing... it is unfair if you leave halfway saying 'gotta go work, cya!' I mean sure there are a few things that can come unexpected but mostly you shouldn't be mixing if you have plans. To me it makes sense to add this, this will make players think twice before joining, 'Will I be able to stay for the mix?' 'Do I have plans?' then people can have a proper 5v5 mix in ambrosia rather than being invited to find out that 5 minutes later they have to leave because the mix has been abandoned, I mean I do not mind if this is not implemented but I think it will convince players to stay, or not join because they have plans. As I said, I play mainly on 5 lithuanian mix servers, 3 from 1 site 2 from other, the site with 3 servers has not implemented this system and has many leavers, whereas the 2 servers with the plugin have wayyy less leavers...
I think this would a great option, I support for adding it if possible. 
Thank you!
Baning them for 5 days is to long tho, I suggest at least to ban them for 1 hour. Cuz it's really annoiyng, if they do want to mix, they should mix and not leave, no matter if teams are to unfair
Yeah 5 days is a long time, a few hours is better.
Counter strike - MIX is the LAST thing I will think off or care about.. I have my family, friends, obligations, work, WC ( taking poop )..
Mhm, the thing is, if we have a system like this implemented this means more serious players will come, I mean a mix is a place where I like to play against good and competitive players, if you do not care about the mix then you should just play public imo, if you're a busy person it is unfair for 9 others to be left hanging because you felt like you want to go out with friends or w/e.
EDIT: I just want to put emphasis on the 10 minutes or so you have to return, it will mean if your power goes out or internet or w/e, or if you have to take a p00 then you have the time.
