I want to know exactly how and when I can see an enemy and exactly how far away.
Noone can tell you EXACTLY how far away, even when it works properly. It depends on too many things. My friend and I did some tests (in 1v1 training battles) some weeks ago (before the latest patch). He was in his Jagdpz IV and I was in Jagdpanther. Both had 100% crew and camo net on. The results varied A LOT depending on what kind of vehicle we used, what kind of bush we used and the angle.
I don’t remember the exact numbers now but there was a range where I couldn’t see him even when he fired (about 200m), at that same range he could see me firing - I would pop out for about 5 sec. If he didn’t fire I would spot him at about 70m, he spots me at 130 or so. Behind some bushes (and at certain angles) he could spin in place while remaining hidden, change any of that and him turning 5 degree would unveil them. Not sitting properly behind the bush (leaving a tiny bit of the front plate out) would greatly increase the detection range.
Someone approaching you head on would spot you at let’s say 100m, someone approaching from, for example, 10 degree angle could spot you from 400m depending on situation.
You didn’t mention which VK you were using but all of them are significantly bigger than the Jagdpz IV, so you won’t get great results from hiding even under ideal circumstances.
Their detection system is probably the worst feature of the game, even worse than the arty, which is hard. :) It’s too arbitrary, uncertain and at the same time too “black and white” for the lack of a better word. You are either 100% hidden and noone can see you even from 100m away or all of a sudden, you are visible and every freaking enemy can see you, even if they are a mile away.
Also the detection system is probably the main reason why we don’t have smoke in the game.
And again, IMO, this detection system was designed to support arty, since they are the only ones who need to be able to see an enemy from a mile away.
If their goal is to create Counterstrike with tanks, these two features (arty and detection system) certainly don’t belong here. And that’s IMO their biggest problem - their feature set doesn’t align with the goal and as a result, people (like TheWombat above) start thinking “This game could have been so much more”, when, in reality, if they don’t want to make it so much more, it should have been so much less - simpler but more cohesive.
