I completely agree.
I never felt that the content added in XI (or EQ, EQ2, LOTRO, etc) was really all that much to begin with. It just took longer to complete the added content. Personally, I think that the reason MMO subscriptions are up is because the games are more accessible (in part, easier). You don't need to set aside large swaths of time at a specific time to actually complete it.
We set the times we want to raid.
We don't need to re-earn the experience lost.
We don't need to re-farm tokens from other raid bosses lost when we failed to clear.
We don't even need to travel to where the raid is.
Mind you, these are just raid-specific comments. It goes beyond that. I'm not insinuating that raiding is easy. However, it IS very accessible to the playerbase.
