First of all it doesn't matter from which country the players are because this nasty Foreigners are humans just like you.

If you go into the DF and join a Group with 3 other People who want to do it fast, you have to keep up to their pace because its 3 > 1 and you don't have to wonder if these 3 decide to not play with you. You find it disgusting that they want to do it fast and they find it disgusting that you want to do it slow.

If you want to do it your own way then just make a group with your friends or a group in the partyfinder to avoid speedruns.
