Eatingualive you win the thred, Although i will not contest the issues that have been brought up about game advancment. As conetent becomes "OLD" and the process of leveling becomes faster and faster(players learn how to level faster) the desire to play the 20-50 instances realy falls though the floor. Fristly becasue they have all been played out, seconly the players know they will outlevle the equptment very fast. For example my most recent toon is a Blood Knight, I ran a instance 3 times to get a peice of mail armor i wanted. then as soon as i got it i had almost hit 40 and now wanted plate. 2 years ago before players knew how to level at max speed i may have been running arround in heords helmet for a few weaks, but now it is a matter of days. So why run a instance time and time again when your gear will be replaced? Whelp if Bliz put super huge questlines in the game that required you to complete instances before you coudl get in the next level of instances.... you would not mind doing them, yet that brings us to the point Eatingualive made.....Sunken Temple is the SUCK.
ST was in the original releace of instances, heck it was the second hardest non raid instance in the game, but they realy mucked it up, they added MARA. the loot was better, the layout was more modular(you didnt have to do all of mara, jsut the parts you watned, while ST only had one way to complete it,kill the trolls then go though the barrier, overall not a whole lot of verity). Mara had all kinds of fun mobs that required tatics while ST was just your standard instance run. Alliance may not hate ST as much as the horde, buecasue if you bring a tauren in to ST you are pretty boned, the little hallways suck.
So a ST recap
:Pretty crappy drops
:takes WAY too long, and there is no modular aspect
:Vision issues
:and a questline that looks like it could be epic but goes noplace.
Hell bliz even put the level 50 quests in the game to get folks in to ST, and that worked till TBC came out.
Some ideas for ST.
a Raid Cannot spawn Hakkar in ZG unless EVERY member of the raid has completed the Chained Essense of Eucranis quest in ST.
make killing the (Gaurdian) trolls give a amulet that opens the barrier(this would realy open up a issue of farming).
Buff the drops
Change the mobs a lil(essentaly by looks)
Widen the halls.
ST can be a fun isntance, and has one of the best stories in the game(so much so that they even expanded on it for ZG, ok they kept up the same story from ZF and the hinderlands) Unfortuanly the place just dose not seem finished.
I always thought that Bliz should include a "Second Run" in any isntance past SM. This would let players return at later levels and accomplish some advanced goal. My example would be taking a artifact from ZG back in to the sunken temple in a attempt to banish the blood god, at the end of the instance the player with the item would use it and spawn a special gauardian... Ta Daaa look you have given new live to the sunken temple.
