Greetings from Germany. I play D2 and it has trade, pvp, trist, cows, baal, rush without lobby. I play with fellow Germans on Projekt Diablo 2 mod and use discord for everything, grouping, pvp, cows, leveling, trist runs. No need for lobby game when we have big community. Make lots of freunden and network. Console will not have traditional lobby but it does not need them to be connect people together.
No worry, game will be successful as it already is on mod. No need lobby at all. Lots of smart people use apps to connect. Its all good.
