Why is it necessary to bring back these instances? Am I saying I hate ZG and ZA? No way, in fact ZA is one of my favourite dungeons to this day. I just don't understand it. Why not take the redesigned boss fights they made for these dungeons and apply them to an entirely independent new dungeon. I just don't like recycled content. Old content that is reintroduced is not NEW content.
Blizzard doing things like this worries me. Not worries in the way of I'm freaking out or threatening rage quitting, just worries me in a way of the direction they're taking the game. The "new" dungeons seem catered to the "new" WoW player. The ones that are Wrath-babies (my apologies if this is you, I mean no harm) or even Cataclysm-babies. They're saying "Hey these were great instances, so we're gonna redesign them and update them so people can run them again." This is great... for everyone but people that already spent countless hours already in those instances when they first came out. I understand they're redesigned but they're still the same instance. Put these new bosses and loot into a new Zul instance... name it like Zul'John or something, it doesn't matter. No one would know the difference.
I guess to sum up that last paragraph: Blizzard redesigning old dungeons is supporting newer players but leaving veterans unfulfilled. Which seems to be a major theme in Cataclysm. I just feel like the long time fans are left in the dust. Honestly I feel like Blizzard needs to implement a few new things that change the game and make it a bit intuitive to keep it fresh.
What's just around the corner for WoW if this is popular for them and they deem this a success? The next expansion could be "Return to Outlands" where they redesign Outlands and all the raid progression will be as before... but don't worry guys, there will be NEW LOOT AND MOUNTS. Then after that? "Wrath of the Wrath of the Lich King"? Where Bolvar is causing problems in Northrend and we have to go kill him while "enjoying" a redesigned Northrend? This potential 'Tol'Barad PvP' style of game design may be (honestly) severely exaggerated, it sadly might not be too far off. This future would be awesome for the new player (which seems to be Blizzard's new demographic) but terrible for the people who have been there done that.
Which, for the record I'll say now, if I ever have to go to Northrend again for anything relevant I will just quit on the spot. I hate that place with passion. I'd rather go raid the library, it would be more fun than that dull place.
Alas, yes I will run these dungeons, yes I will probably enjoy them. But I feel like more could have been done. The recycling of dungeons feels like, to me, a Disney Movie from their "magic Disney movie DVD vault". They randomly get reintroduced to the current public with more and more features and you buy into them because they are your old favourites and, admittedly, that super cool Hakkar poster would look nice on your wall (and sucks you in deeper). But in the end was a new product made?
No, just an old one upgraded then published as if it were.
And this doesn't sit well with me if this is the future for my beloved Azeroth.
