Hey there!
Which side has the better sized population?
League, that means empire needs your help make it bigger
Which class is the most Rogue/Thief/Assassination like?
Like Aoionwen said, demo for the stealth, but Scout has that too. Scout would be my main answer.
Is there Housing or something similar in the game?
The allods online housing style is the Private Allod. You build a maze for people to invade and you kinda live in the office as its your house.
I've seen screenshots of motorcycles, hover bikes, etc...are these specific to a class or can anyone get them?
Anyone can get them
Is there flying in the game?
Like Aion said, Private allod but also in Irene as a fire bird. Sadly other zones aren't. Really should tho. We've seen they can do it
Can someone point me to a map of the game world? Just curious to see the size of things.
This is Suslanger. The recently added zone. It's huge
See you ingame!
