@Stug Life Err yes they can buddy its called ambush training. As an example for you as you can use it with Jager infantry doctrine.
And yes I've over 2000 hours and ive been rank one several times. What about you? rank 1000, 2000? Get off this thread.
You should really get off your high horse, mate.
To your point:
I don't see a huge issue. The camo units are pretty balanced at the moment. There's not much reason to change that mechanic.
Snipers are a topic for themselves, quite a few would like to get rid of them completely.
The only problem with camo that I see are late stage team games, where yellow cover is basically everywhere due to arty.
