Of most interest to me were the following:
For Volume 3: Book 2 we've renamed the Skirmish Join panel to Instance Join panel. Within it are two tabs, Classic and Skirmish. The Skirmish tab has all the functionality of the previous Skirmish Join Panel. The new Classic tab includes every replayable instance in the game, including all instances from Shadows of Angmar through Mines of Moria and Siege of Mirkwood - 39 entries in all! Every 3, 6, and 12 man replayable instance in the game is now accessible through Instance Join.
The former because WoW's Random Dungeon Finder is one of my favourite additions to the game. Never really ran any instances in groups before it, have done heaps of them since.Skirmishes are now available at level 20!
The Skirmish tutorials can now be completed as soon as a character reaches level 20. Once a character completes the tutorial they will have access to The Siege of Gondamon and Trouble in Tuckborough. The Stand at Amon Sûl Skirmish is now available at level 25.
Now LOTRO has it! Or something sort of similar, at any rate.
The latter change interests me because my main character is only level 21 so he's not had a chance to try Skirmishes yet. Can now!
Lots of other interesting changes as well, including some big changes to the Captain class.
So who else is looking forward to this?
