I can see both POV's on this and both are valid to a degree. I think the key to making SoW a success would be flexibility. I would like to see the following when it comes to load outs for both offline and online:
Historical option:
Have the ability to lock ordinance. This would mean if it wasn’t used historically it’s not available period. No mix and match ability.
What if option:
Have the ability to mix and match ordinance but with historical limitations, i.e. if the ordinance wasn't available at that time or in that theatre then you can't use it. While still using historical ordinance, you have the ability to load a G6 with gun pods and a SC250kg.
Free for all option:
Have the ability to go nuts. Here you could use whatever ordinance will fit no matter the historical side of it. Load Mk-108’s in the FW-190 A1, 2 or 3. It’s not historical but then again it’s not meant to be.
With all of these options, however, there is also the user’s setting of the FM. Obviously if you select full real then there should be a an indicator like a bar that climbs to the a cut off where it's simply say’s your too heavy or it’s unsafe to fly.
Flexibility is the key I think, anyone from the single player to server mods should have the ability to choose these options. After all how historical are labels and padlocking?
