I popped into the SEA earlier to try things out.
It's very hard to get from 1 V-field to a nearby one. There are marshes in between them (no idea why!!), there are the reinforced enbankments around most of the field, that you cannot get past, and there are winding roads and obstructions from something that you can see visually but not get to.
Very frustrating.
I noticed 1 thing: I could not man the 8" gun at the V-field. It let me select the 37mm guns but wouldn't recognize me clicking on the 8" gun.
On other problem: It's nearly impossible to manuver inside the reinforced embankments around V-fields (where you're supposed to park your tank?) because it's too narrow. Maybe it's easier in a T-34, but I was in a panzr. I ended up getting flipped upside down because I gently nudged one side.
I think I'll avoid the GV war on this one. I think I'll focus on IL2 GV pounding!!!
