That is how the system should deal with AFK.
I think the solution is simple.
For the draft solo / duo mode (also ranked games) it would be enough if:
AFK
- should not have possibility to join the game after 3 minutes if he was offline from the beginning (early is very important) or for example 5 minutes during the game (after 3 min)
- punishing by eg loss of essence points or even experience
- punishing by some kind of penalty points, and after collecting a certain number of them - suspend account temporarily
Team with AFK - draft / ranking game solo / duo is based on a random selection of players and they are do not know each other, while in the case of 5-players flexible games the team should be responsible for their affection:
- if they would lose - they should not lose points, and they should even get them for the loss of time
- if they would win, and afk left the game, eg 10 minutes before its end (depending on how long the game would last) - they should receive: experience points
Team without AFK
- if they won, they should be rewarded in the normal way
- if they loses, they should lose more points
To base the matches on such rules would eliminate the presence of a troll as it would result in suspension of the account.
Better - not press "No" but - leave your suggestions if I missed something - I will correct my idea straight away in other way it will be easy to guess that people who pressed "No" and do not want chang problem - are simply trolls.
