Hello,
Coming from a long line of MMOs that I've played through the years, I must say, ESO is by far the most restrictive game when it comes to group questing. Not only that each of the group members have to complete the quest separately, but also doing any quest while your friend is not online, will mean that you've left him behind. If the quest is part of a chain quest, that means you'll be phased out and won't be even able to see each other while grouped.
I know the devs were trying to bridge the whole single player/ mmo gap, but it looks to me like the single player side has way too much emphasis in this game, to the point where grouping is mostly useless. This is an MMO after all, and it should be treated as such. Grouping with your friends should be fun, not restrictive. You should be able to redo quests from areas you've already completed. You should be able to get the quest completion if your group member completes the task in your vicinity.
Right now I cannot play while my friend isn't online, because we want to complete the quests together, so we won't get synced out. This is by far the worst feature (or lack of features) in this game for me. I really hope the developers plan to fix this, and allow people that want to group (in an mmo) to actually play grouped outside dungeons as well.
Best regards,
Zak.
