Upgrade battle field length.

in the battle command dialog, there is info such as battle field, which is always same. i think it may be good if the field length can be upgraded.

Actually the field differs depending on each players shooting range. . .so take the person with the best range in the battle, and add 300 to it. . . and thats the field length I believe. . .hope I made that easy enough to understand

Oh, ok i never knew about that. btw, if i upgrade "Shooting Skill" in tech, then the turrets range differ? or the skill only affect Shooting Troops such as Archer and Catpart?

I think it's everything but I could be wrong

Shooting if I'm correct affects archers cats and turrets
