We all remember certain questlines.
We remember them not because of the loot we got in the end or the experience points they gave, we remember them because of their epic scale and how much we had to work and travel to complete them. They where not something everyone did, in some cases very few got around to completing them (for example Dungeon Set 2).
A lot of old old-world quests had you traveling all over Azeroth. Some of these where just normal quests that where just annoying to complete and completely broke you off from the area you where questing in to deliver some package or something to someone on the other side of the world. For just normal quests this was not very good.
However for end level questlines that the developers had put extra time in to developing and that had a great story this was very cool.
The reason this was so cool was because it brought depth to the world around you, it made it feel more alive. A lot of them made sure to be annoying and difficult, this was a great thing since that made you feel as if though you had actually completed something special. Another huge factor in this was how they often started off as unassuming average quests that didn’t seem like anything special and also how “un required” the quest rewards where.
When Cataclysm came and remade the old world and its quests most, if not all, of these kind of questlines where lost. They might have been breaking with what the forward jump in time that occurred and changes to the zones had brought, they might have been dropped due to the fact that they did not bring any end game rewards or they might have been dropped because of the fact that they where too messy for newer players to complete.
Cataclysm quests where at first very appealing and interesting to me due to how streamlined they where, but after a while I realized that it was all a railroad. Jump on and ride along but no choices are allowed.
Where is the forsaken in Kalimdor that in the middle of a questing zone convinces me to take up the banner of the banshee queen as an undercover agent and travel to Eastern Kingdoms to start a whole new line of quests instead?
Why can’t I choose a faction to support and, maybe not exclusively, quest for all over Azeroth from for example level 15 to 60 (tabards don’t give faction specific quests) and upon reaching exalted get access to a specific questline (levels 58, 68, 78 and 85) with a unique reward?
In summary.
Generally questing should not be a pain, but sometimes it should!
