Have been playing on Nos since approx 1 month after it opened...
My guild was the 3rd guild to kill Nefarian when BWL was released (playing a MT, same as i did on vanilla all those years ago), we have been prepping for AQ40 and were participating on the PTR testing each boss b4 it was released
When i rolled the character last April i always told myself "it will not be the same as retail vanilla" and i was so wrg. It really was like playing all those years ago and more....
I played retail clearing 2 wings in Naxx prior to TBC being released. Clearing Naxx was behind my motivation to roll on Nos (which i may add is my first private server exp) and even tho i didnt achieve that goal, the journey Nos gave me was so much more than i could have expected, the same if not better than vanilla retail. I met great people who i will remain friends with for many years to come, participated in great world events such as Emerald Dragons, Kazzak, Azu and also enjoyed great world pvp.
The satisfaction of 8/8 of Wrath + my Chromaggus shield was still like it was wayyyy back then also
The average 8-9k (13k at points during the day) people on the server daily enhanced the experience, the world was alive, grps being ran constantly both for raids and all dungeons (and i mean all), lots of trade both on AH and in /2, constant interaction with the chars around you...
I am devistated it has been shut down but if brings attention to a service which is crying out to be supplied then it was all worth it
Just thought id share my exp with you guys
May i add i was playing on a Acer XR34 which also enhanced the xp
