Stop talking non-sense. I watched DLM tournaments regularly and sometimes connection error did happen. Also more often happen in the country with bad internet
I had disconnection problem with mobile then I switched to wifi and lost 2 other duels, then I gave up my personal goal to enter in the top 10.000. About 15.000 points are needed and I was over 10.000 before start losing for no reason. Maybe playing with pc is better than with the phone, even if this is first a mobile game...
Played today with steam with the same wifi wich I had problem yesterday with the smartphone and was all ok. I even won a duel for opponent's disconection. I think the mobile version have some problems.
