I voted yes. I am very much a solo player. I enjoy being able to trade, chat with friends, help lower level players thru dungeons when i can and generally interact with other players in the game. I very rarely get a large block of uninterrupted time where I can commit myself fully to a group dungeon. I feel that shouldn't hold me back from being able to get at least some of the decent gear in the game. I am fine with Story Mode giving less loot and less relics. That makes total sense to me as a solo vs. group dungeon. I understand I will have to run the dungeon solo many more times to gain the relics, but that is a choice I make going solo.
I also disagree with taking away the weekly quest choice in the story mode. Again, as a solo player I believe I should still have the ability to get things like flakes so I can eventually get my gear together. Maybe a suggestion is to make the weekly's limited to once a week per account, instead of per character (so each player can only do the weekly once, instead of once on each character)? Just a thought!
