Here's what I said for arty:
I hear you on scale, and that was my first response before I thought it through and decided, there is more than one way to approach this after all, not all things ARE scaled, some are... for balance. Arty needn't be in another approach
1/ Faster aim and fire...
2/ settle margins like in mg34 and 42 means after the dial is rotated the arty gunner/ or mortar crew/man needs to wait for the gun to settle to get perfect aim a la the current system, otherwise he gets deviation
/ the speed of settle depends on the piece: Mortar settles faster than howitzers
/This settle only occurs slightly after each shot since, lets face it, there IS recoil, so if he expects successive shots to land right at the same spot, he needs to pace himself i.e current speed, or the shots land quite close, but not right on
/Deviation is minimal, not insane deviation, realistic deviation for the scaled game
/The faster you swivel the gun, the wider the margins go, the greater the wait time to reduce deviation. Arty would relaod faster than now, but to get perfect shots, you will have the current delay time
/closer shots and short adjust-fire spots would require minimal swivel and therfore have shots landing very close to one another as opposed to jumping between spots...
first shot in heated game would be like the first pancake... take it for granted: it wolud be off target, unless you are patient enough, since the deviation would be greatest after first adjustment. Recoil does little to the wait time, so although it causes innaccuracy, not as much as swiveling te gun
