This quest line simply never activated for me. The scout never approached me and is no-where to be seen. I have run through the area several times, and also waited around. When I use the nearby wayshrine I hear someone shout 'hey, wait, I need to talk to you', as the loading screen comes up.
Pretty annoyed. I've played through to level 41 and boulderfalls is meant to be a level 38 area. I'm now a 3rd of a level under where I should be for the rest of the game, most likely impacting my ability to do bosses etc. It's just poor design. Entire quest lines should not be reliant on an npc running up to you in the wilderness, nor should they be impacted by you doing quests in an order other than the designers expected - given you can explore outside of level restrictions. Their is scope in the game to go to Fort A rather than Fort B first and vice-versa (if this is what is causing the issue). The game doesn't work like TERA so don't design the quests like it does!
Cannot get the achievement for quests now, and I'll never feel that this area is complete. Zenimax, heads up to you this - this is very important in MMO's. A big part of the draw factor is wanting to feel a sense of completion. I cannot get this in this area now.
This game hasn't got much more time to sort itself out as far as I'm concerned. I also missed the quest completion achievement in Shadowfen because I missed two little bridging quests (go here, get 63 gold type) due to my route. I missed it in Deshaan because a random npc encounter I'm meant to have simply never activated (again, run around the place 3/4 times and waited around for it in places others got the quest).
Fix it. Most people in my guild are considering un-subbing.
