I won't bash on your development team or talk about how you've moved developers to other projects. Instead I will talk about what you have been doing with Cataclysm.
You have had less leveling zones and quests in Cata. Northrend had more quests and more zones (and no, the rehash of all the 1-60 leveling quests does not count as new content). This has a very large impact on both the leveling experience as well as the end game. While leveling I barely had to put in any time or effort to finish all the quests and content while leveling to max. The entire process was much easier and quicker than any other expansion. As for the end game, I'm tired of farming the same tiny area for herbs. Seriously Uldum and Whiptail? Shimmering Expanse and Azshara's Veil? These are tiny areas that I will be forced to farm endlessly for the next 2 years because your development team was lazy in implementing new content.
Areas to cover in 5 levels of Cataclysm:
Areas to cover in 10 levels in Wrath of the Lich King:
...and Crystalsong Forest doesn't really count.
Areas covered in 10 levels in Burning Crusade:
Blade's Edge Mountains
So the zone/level ratio is about 1:1 in both Cata and Wrath, both of which had more zones per level than Burning Crusade.
We only had to go up 5 levels in Cata, and we got about the same amount of zones per level as in Wrath. We got fewer total number of zones, but what do you expect for only 5 levels? 10 zones? 20?
For questing, just going by the achievements, Cataclysm zones had about 120 quests per zone on average. Wrath had about 100 on average. So we have more quests per zone in Cataclysm. It's a smaller total number of quests, but again, we're only going up 5 levels instead of 10. Btw, both Cata and Wrath have more quests per zone than Burning Crusade, where the average number of quests per zone is about 85-90.
In terms of size of the zone... you think the Shimmering Expanse and Uldum are tiny? Maybe it feels like that because there's so much variety in those zones that each area feels like a zone in itself. There is more variety and creativity on every zone released in Cataclysm than there was in Burning Crusade or Wrath.
Beyond the leveling and world experience, there was a complete lack of interesting and new dungeons added in Cata. 7 new dungeons. That's it. 7. But I had to grind them all over and over because the only way to gear up for raids was to grind rep, and grind rep I did. The same 7 LONG and SLOW instances with almost no option for daily quests.
Burning Crusade had 15 instances at launch:
About 1.5 instances per level.
Wrath had 12 at launch:
Ahn-kahet: The Old Kingdom
The Violet Hold
Halls of Stone
Halls of Lightning
The Culling of Stratholme
About 1.2 instances per level.
As you point out, Cataclysm has 7:
Throne of the Tides
Halls of Origination
Lost City of the Tol'vir
Over 5 levels, that's still 1.4 instances per level. While it's fewer total instances, it's more instances per level than Wrath, and just slightly less than BC.
Burning Crusade only added one instance throughout the entire two years of the expansion; Magister's Terrace. Wrath added 4; Trial of the Champion and the 3 Icecrown instances (which were the best in the expansion, imo). We had to wait until the end of BC to get MgT, and until 3.2 to get ToC. Now, we're getting ZG and ZA in 4.1.
Yeah, it doesn't feel good to get recycled zones, with scenery that we've seen for the last several years. And the addition of new boss mechanics only slightly mitigates that. I'm not too thrilled at the idea, but it doesn't mean that Blizz is "abandoning" the playerbase.
Finally the raid tier. This tier of content is a joke. Our guild raids 7.5 hours a week and started our first 25man raid on the 12th of January. That's 60 hours of raiding and we're working on heroic modes... And let me tell you, from all the research I've done, they are not something exciting to look for. No new mechanics, just bigger numbers and slight alterations to the fights. ULD came out 6 months after WotLK launched. We're already 5 months waiting and are being told we have even more to wait for... and what we are being told we are waiting for is all rehashed content. Rehashed versions of ZG, ZA and MC... Do you guys understand why everyone is upset? We're upset because you provided absolutely no PvE content this time around and the thing you are making us wait for is all rehashed versions of things that already exist.
The sound levels on Atremedes isn't a new mechanic? The Nefarian fight doesn't have any new mechanics? Having three different raid instances to go to instead of one (Naxx at Wrath launch) isn't enough PvE content for you? Here's where you really sound like a spoiled, entitled brat. Maybe you've run out of things to do, or maybe you're burned out, or maybe you're just losing interest in the game. But don't go trying to speak for everyone by saying "we're upset". "We" are not upset. *YOU* are upset, and that's fine. But if you're going to have a temper tantrum, at least try to keep things in perspective.
I'm not happy with the upcoming ZG and ZA revamps either, but there's no way to reasonably say that there is *no* new PvE content, or that the stuff we've gotten in Cata isn't at least on par with what we've gotten in BC and Wrath. Not to mention an entirely updated 1-60 experience which, while it may not matter to you personally, is a huge amount of content for a lot of other people. The developers at Blizzard deserve a lot more credit than what you're giving them in your whining rant.
