I agree the learning curve for arma is pretty big,then there is all the things exile adds.
Now you are also playing on a server with 100+ tweaks modded weapons and vehicles.
There are organized squads that play daily and don't really die or lose there gear unless they run in one of the other organized squads.
The server seems to be catered towards this competitive gameplay and that is why most of us play it.
This means the server is more balanced against organized groups and less towards new learning solo players or small groups.
Hence why removing kill distance and removing player-scan will never happen as they are tools for the advanced players to triangulate noobs and slaughter them in big numbers.
Dont get me wrong i like this CHESS side of the gameplay and this is why i am moderately effective as a console player still playing with a xbox controller but i see your problem.
Tip: Join a decent group and your opinion will probably change.
