furby! when are you coming back?!?
hi there walter. for starters, welcome to AH
night is not currently setup in the MA (there is night in AH, it's just that the main arenas don't use it, too many people whine about not being able to see!
there's no halifax, but lancs are included in AH and play a large role as a heavy buff.
there are no dedicated lanc squad that i know of, atleast no well known or large ones. in AH as a bomber pilot, you control everything, not just the flying. you need to navigate, man the gun turrets for defense, do the bombsite calibration and bomb drop etc.
there are however a number of buff squads. i suggest you start your search there. most of them will be american 8th AF based squads, but they are a good place to get started in AH. if you're still interested in a lancaster squad, you could always start one up after a while.
so if you're into bombers, you should have plenty to do and should enjoy it
have you created an account yet? if not, there's a 2 week free trial with no credit card info needed, so you can try AH and see what you think.
learning curve is steep, much steeper than the arcade games you played before, so expect the game to be pretty hard for the first few weeks. hooking up with a good buff squad will help you learn what to do a lot faster. good luck mate!
