5 minutes.
Why? Becouse if I just have to leave for something in house, im sure to be back in 5 minutes. If its a bigger job, you should realize that you cant play while working with something else.
If the limit is 10 minutes and punishment is harder, it will just punish harder people who forgot they had macros/game running and left their house for whatever reason. Like for instance I forgot to log off last weekend when I went to buy a pizza (I was a bit drunk
Thats my explanation!)
5 minutes is fair time for anyone who is training to actually need to check their screen - even becouse of possible roleplay encounter. Instead of easier "half afk macroing", I dont want harder punishment for people just completely forgetting your macros.
