I made an alt this last time through. Some improvements are simple, some a little less simple.

* Allow us to join the other person in instances.... it's a pain to tell them "now run out of the Solar and through a door on the right... look for Yda sitting on a box and take her blue quest" or "Alpi is hiding to the left as you run out of the Solar, he is easy to miss, but unless you take his MSQ quest we will waste 45 minutes trying to work out what's wrong"

(This was how it was in 2013, we could all stand in the solar together, beats me why they took that out and put us in solo instances)

* Allow us the ability to look in the other person's quest log (like Rift) even to the point of being able to join a quest they have without needing to say "Please don't take this teleport, I am just going to roar into mor dhona and pick up the quest then do a few steps to be where you are, I will be right back".

* For light parties only, give us the ability to grab one or two of our own squadron and use them in a dungeon instead of real people; To be a full party, at our own speed, without bothering two level 80s who just want to get through it fast as possible. But keep the full parties and alliances as they are.

(Is this really so hard, or bad? Duoing dungeons with my new to MMO friend has helped so much. Without the time pressure there is an ability to actually take it slow and teach)
