Main problem I can find with trying to run the software for arma 3 is the reporting ip keeps trying to revert to either a private, <> or an arma 2 reporting ip. I have tried manually correcting the reporting IP within the config and each launch it erases and reverts back to <>. Seems to work flawlessly otherwise. I tried brute force by write protecting the config file and it cursed at me with a nasty exception error. I tried to locate the specific line in the default file but couldn't transcribe which line number the reporting ip is.
Another suggestion, how about adding negative integers to the combat side so you can reduce the incredibly high accuracy of enemies on regular difficulty settings. Seems latest patch made them all crackshot snipers with the ability to snipe you out of vehicles at over 1 click out. Would definitely give much finer tuning control of how you want the server to play out either easier or harder.
