They did say they are going to bring in xp chains, so as long as party sp > solo sp I think parties will be fine. I agree, the more options you give the better.

Only have an hour to play, run a leve or two.

Have a few hours, form a party and link, or go farm on some mobs, perhaps even run a dungeon.

While they will need to adjust/balance the systems to keep everything working and not giving any one system the advantage, I feel that by continually introducing new content players will find that they have lots of options.

Looking forward to September 30th for the one year anniversary and to see how far we have come.
