Problem with most, if not all, of these is that it is not the level ballance team is working on. They have the access to mod tools, not engine source code. That is why Mr.Smith told you that you can provide a fix - becouse all the tools he has, the mod builder, are also at your disposal. Theorycrafting without seeing it from mod tools perspective isn't going to change much.
I gotta say I find it awesome that people from the community are actually constantly working on the game. of course Theorycrafting isn't great, but if people with the tools can do something about it, great, if not, oh well worth a shot.
I have no clue what it takes, I have modded once before in COH1 for about a week and forgot everything. I would still like to see what MR Smith has to say about my suggestions. I am sure if he can code a satchel sticking onto a vehicle, he can set some parameters in there.
