Out With the Old: Major Quest Changes Inbound

As you're all aware by now, the shattering of Azeroth will drastically and permanently alter the continents of Kalimdor and the Eastern Kingdoms. In the wake of Deathwing's devastation, adventurers will be summoned to embark on new quests from levels 1 to 60 in these transformed territories -- and with so much new content to be found on these original two continents, many original quests will no longer be available after the shattering occurs. These quests will automatically be removed from your quest log, while any quests you’ve accepted that still exist in Azeroth will remain in your log.
You may be wondering how the shattering will affect the Loremaster achievements. If you've already completed Loremaster of Eastern Kingdoms or Loremaster of Kalimdor, you will not lose your achievements. However, if you've made progress toward these achievements without yet completing them, be aware that any quests that are removed from the game will no longer count toward your progress, so you may see your achievement quest counter drop. If you’re close to earning either of these achievements, we strongly suggest you finish them with great haste, as Deathwing's return is imminent.
In addition, the Loremaster achievements are being redesigned slightly to make them easier to track. Rather than having players complete a huge number of quests throughout a single continent, the criteria will change so that you will instead need to complete a set number of quests in each zone. Once you've earned the achievements for each listed zone on a continent, you will then be awarded the Loremaster achievement for that continent. For those who do have Loremaster of Kalimdor or Eastern Kingdoms completed already, you can still go back and get the new achievements for questing in individual zones on those continents.
We look forward to giving you an opportunity to take on brand new adventures in these classic zones. The times they are a-changin'.

I researched quests I havent completed and the one I dont understand is "He called himself Altrius..." I have this entire chain complete except the first quest. How could this be?
I've written emails and in-game tickets to GMs. What do I do?!

So to sum up, you will NOT BE REPEATING THE SAME QUESTS but some of the ones you've done are being removed and will be deducted from your total count.

Imagine my horror when I logged on the other day and it's down in the 2000's. Blizzard, I understand that there's new content and that quests left the game never to be seen again. I can even live with having to re-do all those quests AGAIN (the same ones!), but for the love of all that is good and holy WHY did you reduce the quest completed counter?
There is no answer other than blatant laziness on your part, and a disrespect for past work. A counter should never go down, it is a record of what a character has done and you've now invalidated the stat completely.
Even though I am amazingly tolerant and look forward to much that Cataclysm brings I will never forgive you for this and I will always remember that you don't care about players like me.

For example: I went to Silithus, and I see Wind Stones are there, but the NPCs to turn stuff in are gone.
With Tier 0.5 the item to summon the NPCs are there, and original NPC in ironforge is there too, but NPCs give no quests.
ZG is obviously gone, but coins etc. are floating around.
In Everlook the dwarf with the epic lvl 60 catalog talks to you and asks you to check the catalog, and there are no quests in the catalog.
So it would be great if there was some clarity to this. For example, if the items that have no purpose would become gray, like dropped spell books have become before.
Another idea would be to not remove those quests at all - after all everything except ZG is still here... But maybe too late for that. It feels very awkward.
With Tier 0.5 while I was working on it, I actually asked a GM if I would have problems completing, and they said that they don't know... I guess should have planned for the worst.

I <love> the new quests so far! Even though I already have 10 level 80's, one of each class, I would make another just for the sake of running these quests! (...and in fact I have...) But really, why force me to blow through these zones at level 80, with no rewards other than achievement points? I'll be ecstatic to experience your new quests...on a toon that is actually at the level range the quests are designed for. Makes no sense to one-shot everything by looking at it funny as a level 80.
Just my viewpoint...

So it appears that its not just that Loremasters must do 1400 more quests that a new character to get the same achievement points, but also has to do the majority of these quests twice. Doesn't really seem fair IMHO.
Blizzard, you have shown that you are willing to listen to the players of WoW - the late change to the 'Insane' achievement proves that. Those people with Loremaster are your bread and butter customers, the ones that stay with you through thick and thin. We dont get bored after a couple of months and move on to another game. This feels like punishment to your loyalist members, a slap in the face we dont deserve.

I understand they want players to experience the new content, but why not wrap it up in a separate achievement? It seems pretty lazy to me, and frankly as one that has liked going for achievements, it is becoming apparent that they may not be worth the effort. You'll either have to redo them or they'll become feats of strength which at this time takes away value. Maybe they plan to have an achievement with a title for people with N or more feats of strength? Who knows?

I decided I didn't mind it so much because the stories are a lot better. Also, the flow throughout a zone is so much smoother. I love it.
