I'm going to elaborate on my idea of the classes, since I just read a lot of your ideas, I've gotten mine up to date, to include a bit of sense. I'm only including Britain, so I'll make another post for Germany after breakfast

. Also, I figured I'd unveil a few of my other class ideas, some that were widely used on both sides

I've also implemented a Kill System, where after a certain amount of kills, you get a medal (medals will serve as currency) and you can use the medal to upgrade your stuff. I know spearing said there wouldn't be any currency, but It is based entirely on kills, and you cannot get medals any other way.

*The assault class suffers from less accuracy, and is slower when carrying Heavy Armor or Flame-thrower
*The sharp-shooter class suffers from a very slow rate of fire, but increased accuracy
*The Machine Gunner Class suffers from very low speed, and has slightly lower health than most classes
*Abilities are activated when a medal is used. Medals can increase damage, speed, or accuracy of weapons permanently for the user, or they can be used on Abilities, activated when a medal is thrown down. (i.e, the medal is like the construction hammer on mmrussia, but a menu is brought up offering weapon upgrades or abilities)
*Medals are gained only by getting kills.
