Warning: Unusually optimistic position here
So, one thing that can compensate for the lack of a raid is the quality of these 10 quests.
The only way I'll stay happy without a raid is if every one of these quests is von3 on steroids - with tons of optionals with kickass xp, amazing loot*, an epic showdown with a boss at the end, traps, diversified encounters, hard to get "secret" areas with bonus chests - (trial by fury in demonweb had this neat aspect to it), secret jump spots that give you shortcuts, hugely involved scenery and detailed artwork etc...
Now, if these quests are like house of rusted blades or impossible demands - then turbine, you guys are lazy and incompetent money grabbers.
* : Alright, for the thousandth time, can we please get some truly epic loot with this expansion? I don't know how else to beg you guys to reassign your loot designer to some other job, and get genasi or someone else thats competent back on the loot designing job.
Theres no raid, so the possibility of uber raid loot is ZERO. These quests are all we got - make them count
