Other issues include you have grown up in the last 8 years and your priorities are no longer the same now as they were when you first started.
When I started my priority was playing as much WoW as possible, and drinking on a weekend, now its looking after my children and fitting in a LFR or Flex after they have gone to bed.
Other issues include creating too many new realms when the olds ones werent actually full enough to warrant more realms, they could have added a couple at a time, but only when the others were peaking out, now we have a lot of dead realms which create an atmosphere of playing even more solo.
Also computer users and people with access over the last 10 years has changed dramatically so the footprint of customers now is not the same as it was in the earlier days.
Another point is that as people became more affluent especially in the earlier part of the decade they had more disposable income so they could do more frivolous things such as playing online games, but once the novelty wore off they werent really sure of the correct nuances and behaviours required of people, which has lead to a steady decline of the nice helpful player and increased the amount of trolls who know what they say online will not get to affect them physically in 99.999999% of cases.
