Tried the mod yesterday, really good job! I agree with LordKhaine on most of his points though.
As this mod is called "Immersion Mod" I have a suggestion. Since the release of Rising Storm I've been playing the game with no HUD at all.
It's a different experience that I suggest people here should try.
No clutter on the screen at all lets you immerse yourself far more than you otherwise could.
I have a script though that shows the HUD when in tactical view or scoreboards etc. so I can access any information when I want it. Only problem with this script is that it gets a bit wonky when server changes maps (if there was a "setHud = true/false" command and not just a toggleHud command it would work perfectly). If anyone wants to try it I can give instructions how to edit RoInput.ini.
Anyway, my suggestion is to add this as a supported feature. I suggest that it should be up to the player if he/she wants to use it, as it makes the game a bit harder (especially if you are new to the game).
What could be done to improve it to work better than my simple script is to add some minimal hud elements for the most important events, and chat etc.
