So I have only been playing WOW for just coming up to four 4 months now. (I played a long time ago until the day Wrath came out and then quit the very day it came out - at that time I was just playing one account).

Then I came back and bought 5 accounts.

When Cata came out and I continued to level up my guys and now I hit 85 and I decided to put my guys on hold while I level my tank's ilvl and general gear because I was finding it too hard to run instances.

Now I just can't find the motivation to play with them any more?

After running all of the instances I think to myself...

Dead Mines... impossible as a multiboxer.
- Good luck clicking all the ropes at the end...
- Good luck moving through the electrostatic turn wheels..
- Good luck avoiding the rotating fire on the first boss and maintaining high amount of AOE dps on the adds while nuking the boss

Grim Batol... good luck with...
- The obscene movement on the third boss and avoiding the fire which consumes 80% of the room and avoiding the elemetal goos which track down your players
- On the fourth boss it is impossible to stack up slowing down the adds reaching the eggs...

Throne of Tides
- The final boss is just impossible

Stonecore
- The final boss.. you have to do about eight things here all at once

So, in complete, I think the only instance on heroic which you can farm as a multiboxer is Vortex Pinnacle. Seeing as I can't get epics unless I run raids with my guys, which blatently won't happen, I can't see how it is going to be possible for me to get any enjoyment out of the game any more multiboxing.

Instead, I am just using my 85's as AH alts and amassing an absolute fortune. I think I'm up to about 120k in liquid gold and I have over 150k on all my guys in statistics for gold acquired, not to mention I just bought 7 BOEs for my Paladin tank this week at 15k average each.

I don't know if I can see the light at the end of the tunnel! But for now, my guys have become glorified bank alts.
