It's not about skill full or anything, people enjoy it, and nobody is going to do normal exp parties if quest grinding is faster.
Sure I will do normal exp parties IF I can get a party.
But Masa it would be impossible to do if I can't get said party. Also, just look at star wars, its purely quests and it's going free to play.

I just want parties to be on par with those quest grindingness. That's not much to ask.

Also sure, there will be quests with parties no duh, but the only reason why you would need a party in a quest would be to kill a boss. They are going to make it solo friendly but if you wanna do quests together you may.
