I see threads all the time talking about how the majority of WoW players don't raid and so forth. If that is the case, and if content was so "unaccessable" back in Vanilla and TBC, how come so many people played for so many years? Vanilla and TBC lasted about 4.5 years until WoTLK came out. How come so many people were subscribed for so long if most of them didnt do any raiding?
The answer is the grind and the journey. The slow, yet steady progress of their characters over time. The expectation that gear was something to be treasured and took patience and effort to obtain. Acquiring new gear was a gem in itself. 5 man content was the end game content for those players. Getting into a managable BRD that could last 3 hours with the hope that maybe 1 or 2 peices of gear would drop for you was the reward.
Getting to 60, and then thinking "ok, so what do i do now?" And having soooo soo many options open to you. Do I work on saving up money for my epic ground mount? Do I work on the paladin / warlock quest chains to obtain my class mount? Do I interact and socalize with people on my server, make some friends, and do some 5 man content to get a new blue upgrade? Do I do some of the challenging group quests that I may have overlooked? Do I try to upgrade my dungeon set through the quest chains? Do I work on getting myself attuned to the several raids so i can be ready to raid later on? Do I enter molten core to just check out the entrance?! Do I find a guild so I can maybe kill some stuff in MC / ZG? etc etc etc.
You understand my point.
