I honestly dont see the point in modeling this plane. I predict after the first month is will be Queen of the hangar Queens.
Much rather of scene Iron Annie instead of a "spotting plane". Who is really going to bother spotting in Aces High? And arent there better options then an airplane with poorer then WW1 performance?
You are easily mistaken, with the BETA arena we see signs of changes in Aces High - Aircraft with bombs cannot see GV's until extremely close (600 yrds)
This puts Storch as a very high value in the game, at 3k you will need spotters to direct ground vehicles instead of someone flying 2k away and seeing the icon.
It might not garnish the kills per tour as a P-51D, but if you want to help friendly tankers defend a base - someone is going to be upping a storch.
It's not a game changer, but does change the overall strategy on taking a base. It will not stop a Horde or etc, however a small furball will see a storch to spot and give supplies out.
As a tanker, I see this as a plus in the game, it adds realism to the game.
