And last night, after 3 years and I cannot count how many Headless Horseman kills, one of mine, finally got the Headless Horseman's mount!
My paladin is the lucky character.
Considering last year, when I tried to get the Plate DPS helm for my Warrior, where my warrior participated in 86 kills of the Headless Horseman - without ever winning the roll for the helm! (Of course this year, my Death Knight got it... go figure...).
I continue to play around with tweaking some settings, but its been very stable. Only irritation I noticed was that it took a long time to re-establish the network connect when it wakes from sleep mode.
I remain very impressed with how stable and bug-free the install has been for me.
