Playing in the DOA beta convinced me to sign up for a WB account. It can be very fun. If you like early war ac, well can't get much earlier than this.

I recognize a lot of handles in AH that used to fly DOA. Rosco, Yeager and others. Had a lot of good fights there. I remember a Baby Harp Seal called Kieren, he couldn't fly a DVA very well. The sad part is he always flamed my butt.
Incendiary ammo and fire modeling are 2 neat features. Never could understand why they didn't port that to WB, like they ported all the WB features to DOA.
