If you've done any programming projects yourself, you know that its much more time consuming to write engine that can have its internals modded later. 3d models, purchasing prices and damage models are this games "core" and like 99% of other games on the market, these cant be modified easily by 3rd party.
Changing code from non-modable to modable takes usually full engine rewrite, where only pure algorithms are "copy pasted". Im very certain, that since this games developers have started more from the "hobby" base, this engine is quite big can of worms to start sorting out.
Btw theres only one or two games that i can think of, which have had any benefit from being completely modable. Trutfully speaking, community pushes mostly utter crap when they have to really start digging up charts, armour stats etc. Just look at the flight sims, only good that inviduals can do are nice 3d models and thats it.
BFC could maybe let community to make skins and 3d models for them in next engine, it would save their precious time. Its more than likely, that currently everything in this game is "hard coded" in it except skins. But ive seen this same whining happen every single time. No matter how perfect the game is and how unique, somebody always thinks that HE couldve done it much better, so this one is really a piece of crap. Its the Fanboy syndrome, before release you praise it to heavens and after release you bash it, since this and that isnt in the game (no matter that no-one never promised such features to be in).
This PBEM issue, no matter how simple it might logically thinking be, can be hard to sort out when you have the actual code in front of you.
