I don’t really understand the recommendation of some here to the OP to increase the difficulty. As far as I understand @Killerz34, it’s not him/her playing the (yet very common) solo adventure W-lock game. This kind of player can be found on any difficulty level. So unfortunately only the private lobby helps. It should actually be the other way around, because if you are obviously not interested in working with the 3 other players, then you can also play solo with bots. These comments here “that you should not/can not impose your way of playing on others” are just as nonsensical and merely provocative, since they apply just as much to the elf player addressed here, who does nothing else with his/her behavior.
Anyway, you can not really change people, look for a team with which you get along @Killerz34 or make the games private, bots are usually the frustration-free alternative anyway.
