First of all my game is messed up for last 4 days..am one of those ppl that gets the black screen of death and have to reboot whole machine.
Second, I prefer solo for the side quests because I go afk often to let my dogs out, laundry, dishwasher etc.
I play mmo's to chat with other ppl, compare notes and do "group" quests. I always help ppl who need it but to quest as a duo all the time would frankly make me too tense...and that is my choice to not hold ppls hands on simple quests that you can fly through. I like to look around and usually find odd things that I enjoy. I am not going to slow someone else down on a regular basis. As it is before the pc freeze..I went on several group quests and tbh, I don't care about getting level this or that by this time, so I felt too rushed and was missing a lot of the story line because of it.
I understand your desire to group but its up to you to find a partner, its not our obligation to do the side quests as a group because its how you like it...not meaning to sound harsh. I have always thought there should be a roster of some kind on the forums for ppl to search for regular leveling partners that way you can set up dates/time.
