I think you should start the server new as 4.0.6, that is the time were you had the most player's online (about12k everyday with a queue on every server)
The problem lies in the 4.3.4 patch if you ask me, it doesn't provide much to do, because running ds for the full gear isn't entertaining, every pve player will tell you that. And what do you have to do besides doing as a pve player?
Questing? There is nothing that gives you any rewards that makes it worth for you to do so. There is just not enough content in 4.3.4, even if you restart the realm and release it as 4.3.4 again, ppl will get bored of it really quickly.
Now that we talked about pve, look at PvP, and the current state of the realm it is completely dominated by the pve gear, bg's and even arena is ruled by half pve geared bros, that just kill you in an opener, leaving no room for the actual skill of a player to shine since, you are mostly dead in cheapshot, kidney, smoke anyway.
Now take a look at 4.0.6 contents that will be actually be played
Pve:
Reputation is relevant
Dungeons are HARD and relevant -> FUN
raids are fun and there are 3 different ones.
Questing in TolBarad is actually rewarding and will make open PvP happen again
PvP
Was a lot more balanced, elite weapon was actually really usefull and no one was running with the insane amount of pve, beacause there were not as many broken pieces. Sure there are strong trinkets, but no ones that just automatically do dmg for you, that is what is really cancerous to play against.(Cunning,nokaleds,gurth,blf,vial)
Do you still have the old 4.0.6 data?
Have a nice day guys!
