As an arena realm, the old warsong with 1k+ people online and 3s queues all the time is dead, most likely forever. Now this thing whatever it is, resurrected or reanimated or w/e is a mere shadow of the glory the server used to have. There like no skilled horde players atm and most of the skilled ally players are leaving too. At least horde has organized some guilds otherwise they would never win a single BG even.
The only thing that can bring back some skilled players on bot sides is implementing AT-core, which however wont happen anytime soon, because all the attention of the staff is about Lordaeron and they wont work on Warsong untill Lordaeron is 100% working, which will take em years to achieve in the best case scenario.
It is nice to see that there are still people is this resurrected and barely alive realm who can organize themselves, but please, do not lie to yourselves - there is none of the old skill left here.
