Hours of waiting in the queue. But just if you're able to get to the queue. In many cases you're not even able to get to the queue. Games says something like: "Can't connect to server due to heavy traffic.". So you need to try several times. If you were lucky and went to the queue you're allowed to wait now. If you passed through the queue you might think something like: "Let's go, now I am going to start to play. Let's do the main quest which wants me to play this dungeon". But you can't join the dungeon for sometimes 30 minutes. Everytime you want to enter the dungeon or go for matchmaking you get an error which says: "can't get location information". You also need to try many times. If you do like 50 times in most cases you can enter the dungeon. If you get a dc you don't have the option to reconnect. You need to go throght the waiting process again. Steams says I "played" the game for 50 hours. Real hours of playing should be something like 15. The rest ist waiting time in the queue.

Zum Russisch lernen ist das game echt nice.
