Okay, so there is a Blog Azeroth Shared topic going on that asks about old-world instances.
Seeing as how I leveled up as restoration, I’ve spent a LOT of time in the original lower level instances. The worst designed of all is the Sunken Temple, more officially known as “The temple of Atal’Hakkar”. I like to (not so fondly) refer to the instance as Sunken Eternity. It’s long, windy, confusing, and really hard for inexperienced players to understand what path to follow, seeing as how there are multiple events that you have to do in a certain order to unlock other bosses. Even after hitting level 60, I still managed to get a group lost in there and spent hours trying to figure out what we needed to kill to unlock the different bosses.
It would really be a shame to go back and re-shape Azeroth, but leave this monstrosity intact to torture people in future generations of WoW newbies.
Here’s a link to the current map, posted on wowwiki.
Yes, it has 5 floors. Yes, you have to do some things to unlock other things. They also have a map showing you how to find the actual instance portal, since it’s buried behind a bunch of trash mobs you have to clear just to get to the instance inside the temple.
What they really need to do is split this into 2 instances. Or, maybe just take it out completely and call it a lost cause (ie. maybe they “sunk” the temple for real this time, and it got swallowed up whole, never to return).
According to wowwiki, there are 10 regular bosses, 6 mini-bosses, and 3 named rare spawns (2 outside & 1 inside the instance). That is almost 19 different boss-type mobs to have to keep track of spread across a bunch of different areas. That’s just way too much for one instance.
So, they should split up some of the floors into different instances. The front entryway could be turned into having different portals. You could even require completion of one side to give you a key for the other side.
They could split up the bosses between the two different wings of the “new” dungeon, so that it seemed a little more evenly split.
Another option (if the developers don’t want to start from scratch) would be to remove the forced completion of certain encounters to unlock other encounters. If you want to go straight for the 4th floor and skip the rest, you should be allowed to do that.
