You get my vote.
I have in many treads lately advocated for a two arena setup. Something which developed in WB after many years of experimenting with arenas an various setups.
Let me describe it again:
One arena is called "The Combat arena". Here you have the full choice of planes, easy mode if you like it, full dot-radar on map, full range icons. All is made easy for those who want to spend the least possible time on finding targets, and who just want a shootout and furballing experience. This is a multi-sided arena as in AHs MA, and is what in WB resembles AHs main arena most.
Then you have the "WW2 Arena". This is a two sided allie/axis arena for those who want the historical aspect and a more challenging flying environment. Here there is a rolling plane set from early to late war during the tour of duty (ToD). Full realism is forced on (no easy mode). Dot-radar on inflight-map is disabled. Only when in tower you have dot-dar. Lethality of guns are reduced to 80% (makes it harder to kill, but more fun i think). Icon range is reduced.
Dont let this down just because it comes from Warbirds. Remember, WB has developed its gameplay for many more years than AH. Learning from others are a good feature, and with regards to these issues Warbirds have good features to be adapted in AH.
Picking the best features from other sims can only enhance AH and secure that it keep its lead as best WW2 planeset sim.
