I am not saying that what I am writing here is what is wrong with the expansion. It is just my opinion of why it feels wrong to me.
It's not so much that they went back and raised the bar on difficulty or any of the numerous QQ reasons you see daily on the boards. I was thinking about it the other day. Why does it feel, not so much wrong in any way, but an off feeling.
Then it kind of hit me. Our brains are on overload, there is just to much to do. They have added so much content spread out to every group of people that wanted something new that the majority of people can't decide what they want to work on, because there is so much to choose from.
You have groups plowing through raiding content so fast that they are screaming they want more, faster, faster, come on Blizz its been a week, we have that on farm, give us new raids.
The PvP crowd has multiple Battlegrounds, Arena's, Rated Battle Grounds, etc. and want more. And with the Justice to Honor convert, most everyone is walking around in full Season 9 or better PvP gear.
There are Zone dailies to unlock new areas, faction dailies for rep to get gear, Cooking and Fishing dailies everywhere, grind grind grind.
Quests all reworked and for many people reset for Loremaster so they need to go back to do them again.
Archeology, yeah lets not go there.
Firelands rep runs, and every caster and their 3rd cousin now has Taragosa's Rest quest.
While there may not be a lot of new level 85 heroic dungeons, they made them exceptionally long so that most groups need an hour or more to do a run.
It all kind of hit me when I logged in for my normal 3-4 hours of playing during the week, I had to get my Hyjal Dalies done, (30 minutes), Tol Barad was up shortly after, followed by Baradin Hold, (about an hour total), Signed up for Rated Battle grounds, (2 hours), leaving me 30 minutes to que up for a Heroic regular which I dropped from Que because it was a 35 minute wait, others were doing a troll and they had thier 5's. That did not include any time to knock out some quests towards zone achievments, farming for mats to earn some cash, or any raids. Its the same thing everyday, just different things going on that I feel I have to do. It has evolved into not so much a game I play to have fun and relax but a Part Time job that I work at 7 days a week.
When I think back the downturn may have been when they lowered riding to level 20. If you wanted to run a dungeon it meant 2 people had to run, or ride there, if you were lucky they had the Flight Plan to there. Something as simple as doing Scarlet Monestary actually took some time to organize. The overall pace of the game was slower. It took me 5 months to level my first toon to 80. Now If I work at one I could probably do it in 2 weeks, 3 to get to 85.
If the game slowed down, would that really be a bad thing?
Anyway, just my thinking.
