I’m fine with the Basic idea, just the 2-5 People I’m not fine with
Make it 1-5 People and let it scale accordingly. There are quite some synergies to be had among the classes already through auras, heals, buffs so that Group Play is encouraged.
I dunno, I love each Season Start in D3, coop with friends with TeamSpeak. Coop with strangers might suck, I don’t know.
People only going in Groups because there is more loot to be had is no fun either. As can be seen in D3 Pubs as well, where you Need very specific builds to not be immediately kicked out, because it’s just about the Speed and the Loot. “Mandatory Group Dungeons” would result in the same I’m afraid.
I think the drop rates of sets and uniques will be lowered down the line, and everything is sped up quite a bit for the sake of beta (reaching Level 60-70 in one day seems a bit quick IMHO), so ideally uniques and sets will have a bit of that wow factor. Legendaries definately will, and I’m fine with Items that have a Mod Level of 18 or more to have a red Label (So 3 T5 and one T3, or 2 T5 and 2 T4)
That should be rare enough to be WOW worthy when it drops, and you can create them yourself with luck, and they are not unnecessary power creep even before the release
