Currently on EQ2's Test Server is the following update:
Kander has lowered the difficulty on Karnor's castle, added a couple of named critters, spread out some of the loot a bit, and thinned some of the population. We'd like to get this zone in shape so that it's more appropriate for smaller groups of players entering that level range. Please take a few friends with you and see what you think of the zone. Do keep in mind that we're shooting for smaller groups of level 72-76 players with average treasured/mastercrafted gear.
If this actually makes it to Live, all I can say is it's about time! And tweaking it for us poor average geared players too! While it existed in the older MMO's, small group content has been absent from nearly all the more recent releases. So you are left with soloing or a three-hour ordeal of waiting for a group to fill and then a long journey ahead. Certainly I can gather two friends to do solo mobs. But really why bother?
I believe many that solo do it because they don't like the only other option available. A large percentage of our guild solos. I can say with certainty that if there was a dungeon three of us could do, and be done in 45 minutes to an hour, the majority would jump at an invitation to do so.
I would really love to see a change to this solo/full group mentality in the future MMO's. Warhammer seems to offer an interesting alternative with their public quests. We'll have to wait and see how that actually plays out. But good to see EQ2 make a change in this direction. It's just one small step, but hopefully there may be more to come.
